Developing Teen Leaders: Expanding the Family Meeting

Whether your children are toddling about beneath your feet or are asking to borrow the family car, organizational skills are a must. We’ve thereby utilized a monthly family meeting since the kids were wee ones to plan holidays, discuss our goals, and essentially take our pulse or discuss any issues or concerns.

Now that my children are a bit older and they are taking on leadership positions of their own, I find myself sitting back and smiling – admiring how the professional skills we’ve implemented into our family life now help them in their academic and social circles.

Using the color coding and invite features, we can improvise when unforeseen changes (sick teachers, additional music lesson, or a Scout Board of Review) are needed. However, we are not always on the same page despite having electronic devices.

Expanding the Monthly Family Meeting

My husband and I have noticed a gap with how to make the upcoming appointments and ‘to do’s’ more tangible for our children. Like us, the kids are more prepared and less stressed when they know what to expect each day. No one likes getting woken for a surprise dental appointment or getting pulled away from a coding issue on their Minecraft server for a haircut. Now that they are older and are beginning to schedule appointments of their own (art lessons, podcast interviews, etc.), we need to be aware of their plans as well.

We tackled this nuance with a family meeting on a weekly basis – or Weekly Overview Review. This meeting takes place next to a whiteboard in the dining room (essentially my VIPKID classroom each morning), and lasts about 15 minutes – usually on Sunday after breakfast, or in the evening if the morning doesn’t work out.

Our shared Apple calendar is color coded and thus using colored markers is a natural extension of our digital schedule system. It helps everyone to visualize the week and understand it better.

The focus is on the coming week, and the board therefore is divided into columns from Monday to Sunday. Everyone enters the most important dates with his or her color and introduces them to the others, e.g. “9-11 volunteer at marine life center”, “6:30 Board Mtg at the hospital”, “piano lessons”, “debate club”. We are thereafter fully engaged and aware of the activities planned through the week.

These revised meetings have been such a success that I’m looking forward to purchasing a magnetic calendar whiteboard. Having a visual reminder that we can refer to throughout the week will also help alleviate conflict. No longer will my son have an excuse to say, “What? I have a doctor apt? You didn’t tell me!”  or “I forgot to look at my calendar. I must have missed the notification.”

Questions We Ask the Children

Once our obligations are recorded on the white board we take time to discuss the details of the week. We also encourage the kids to take more ownership in their learning – to strive for academic and career goals.

Additionally, we all share in the management of the house – doing our part to assure the chores are completed and the burden doesn’t fall on one person’s shoulders. Everyone has a role and helps to contribute to the success of the others.

• What are you doing this week?

• What do you need from us (financial assistance, transportation, etc.)? Are there any permission slips that we have to sign?

• Is there anything from last week that isn’t finished yet?

• Did you schedule time for learning? What creative project(s) are underway? Do you need help studying or with a project?

• Who will take over which household chore in the coming week? 

• What meals would you like this week?

Input in these areas really helps reduce my stress during the week. I’m able to shop for groceries just once (generally) and have a clear plan for the week. No more evenings with me scrambling at the last minute trying to figure out what to cook with what happens to be in the pantry. This also helps assure the menu is more diverse and appealing to everyone.

Questions We Ask Ourselves

As the kids have become more independent, it has also enabled me to go back to work on a part time basis. At first, I was substitute teaching and thus I would be away from home for the full day. This created difficulty in regards to scheduling and transportation. With VIPKID, I rarely substitute anymore but I do volunteer regularly. These obligations require us to sometimes be a little creative or seek out outside support (Grandpa, for example).

• Do either of us have to adjust our weekly plans because an important appointment for the children has been added?

• Do we have to organize outside support on any day?

 

You may think a family meeting like this is too formal. Our experience, however, is that the kids develop a much better understanding of each other’s plans, find their way much better with their own daily lives, and thereby become more independent and self-reliant.

Aquatic Science Studies: 10 Activities for Teens

Aquatic science – the study of wetlands, freshwater and marine systems – can be a little intimidating. With adult supervision and clear boundaries and expectations outlined in advance, taking time to explore these diverse habitats can be very rewarding. The focus of my post today is on aquatic systems – estuaries, ponds, lakes, streams, and rivers.

image of the Sundial Bridge in Redding, California with text overlay Aquatic Science Studies: 10 Activities for Teens @EvaVarga.net

Physical Factors of Aquatic Systems

Abiotic factors are components of a natural environment that are not alive. In other words, abiotic factors are the physical or chemical parts of the environment that affect the organisms in that environment. For aquatic ecosystems, these factors include light levelswater flow ratetemperaturedissolved oxygenacidity (pH), salinity, and depth.

Upper elementary and middle school students are capable of exploring how each of these abiotic factors affect the environment. If you are just getting started, I encourage you to begin with a small pond. Here, children can enjoy the freedom to explore safely while also focusing their attention on specific learning goals – observations and data collection.

The most distinctive area of an aquatic system is likely the riparian zone. Acting as buffers between upland areas and open water, riparian zones help filter pollutants such as nutrients and sediment. Healthy riparian vegetation helps to reduce stream bank erosion and maintain a stable stream channel. Vegetation also provides shade, which works to lower water temperatures.

Conduct a riparian area survey with your students with my guide, The Many Parts of a Stream Bank. This half-day field excursion is a wonderful outdoor science experience for teens.

A few years ago, my STEM Club was immersed in a three part ecology unit, Field, Forest, & Stream. One of their favorite activities in this unit study was the stream survey – after all, we spent much of our time in the stream – the perfect way to cool off in the stifling heat of a Redding summer. Some of the physical factors we investigated were bottom substrate, channel shape, and the velocity of the current.

Flora & Fauna of Aquatic Systems

Move beyond the physical factors to explore the impact these abiotic factors have on the animals and plants that make their home in freshwater streams and rivers. Expand on your stream survey to include the flora (plants) and fauna (animals) of the riparian zone. Take it further by investing how biotic factors such as invasive species affect the native organisms.

Reach out to your local fish and wildlife agency or watershed associations to inquire about their outreach classes and internships. Many provide opportunities for youth to get involved in long-term projects.

For example, my daughter and I recently collaborated with an undergraduate looking at the effects of the invasive European green crab on our local estuaries. We spent the day collecting traps that had been set out the day before and in turn setting them out in new locations. We also collected data related to the abiotic and biotic factors:

  • What crab species are present?
  • What is the water temperature? air temperature?
  • What is the time of day and location?
  • Of the non-natives collected, what is the size and sex distribution?

Design a simple lab experiment to explore how environmental changes affect aquatic organisms. I’ve outlined the procedure in my post, Environmental Science: How Species Respond to Environmental Changes.

Inquiry based science projects like these allow students the opportunity to become the scientist themselves – using the tools and resources of real scientists. For more ideas, here are 100 Science Fair Projects.

Beavers are the largest rodents in North America, and they spend most of their time in the water. Nature’s engineer, the industrious beaver is often cited as an example of a keystone species because through its dam-building behaviors it has major influences on both the vegetation of an area and the water table.

Initiated by the fur trade, the consequences of losing beavers has had a profound impact on our ecology: streams eroded, wetlands dried up, and species from salmon to swans have lost vital habitat. A fabulous non-fiction book for adults and advanced students is Eager: The Surprising, Secret Life of Beavers and Why They MatterThe author outlines the strategies undertaken by scientists, ranchers, and passionate citizens who recognize that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them.

Do you have beavers in your local area? What about the past? How has the range of beavers (or another animal) changed over the years? What impact does its absence or presence have on the ecosystem?

For younger readers, consider Salmon Stream by Carol Reed-Jones. The illustrations and text blend well together to give a great sense of the ecosystem and watershed. Written in cumulative verse, the author has created a book that is enjoyable for students and a valuable teaching resource. Awarded the CBC/NSTA Outstanding Science Trade Book, it provides an accurate description of the life cycle of salmon – from their form as eggs in a stream to the wide ocean, eventually making a hazardous journey home to their stream of origin. At the back is a section on salmon facts and what makes a good habitat for them, teaching the basics of ecology and why clean streams and waters are so important.

To accompany this book, I created a printable you can download FREE to illustrate the life-cycle of salmon.

Seashells on the Sea Shore: The Geological Contributions of Mary Anning

Imagine for a moment, it is the year 1844 and you’re walking down Broad Street in the small coastal town of Lyme Regis on the southern shore of England. Your eyes are drawn to a window of a cottage. Treasures lay on the other side of the glass: coiled ammonite shells long since turned to stone, sea shells carefully arranged in a pattern, and in the center sits the petrified skull of a long-snouted sea reptile with pointed teeth and huge eyes. A sign above the door reads Anning’s Fossil Depot.

This small shop of curiosities was owned by a remarkable woman of her time, Mary Anning. She spent her life collecting the Jurassic-era fossils displayed throughout the small shop, simultaneously providing for her family and unlocking the secrets of Lyme Regis’s ancient past. Today, her shop is a museum.

image of Mary Anning's Plesiosaurus fossil discovery

Born into poverty in a society famed for its class consciousness, the savvy businesswoman defied the odds to become one of the world’s most important scientific figures.

Paleontologist Mary Anning was an impressive fossil hunter who discovered the first articulated plesiosaur and was among the first to identify fossilized poop or coprolite. However, like many females scientists, her male contemporaries had a frustrating way of swiping credit from her.

Short Biography of Mary Anning

Born on the 21st of May 1799, Mary Anning was an English fossil collector and paleontologist. She became known around the world for important finds she made in the fossil beds along the seaside cliffs of the English Channel at Lyme Regis in Southwest England. Her findings contributed to important changes in scientific thinking about prehistoric life and the history of the Earth.

By the late 18th century, Lyme Regis had become a popular seaside resort and many locals supplemented their income by selling what were called “curios” to visitors. These were fossils with colorful local names such as “snake-stones” (ammonites), “devil’s fingers” (belemnites), and “verteberries” (vertebrae). Fossil collecting was a hobby shared by many and it gradually transformed into a science as the importance of fossils to geology and biology was understood.

Her father was a cabinetmaker who supplemented his income by mining the coastal cliff-side fossil beds near the town, and selling his finds to tourists. He married Mary “Molly” Moore in 1793 and together had ten children, though only Mary and one brother, Joseph, survived to adulthood. Their father, Richard, often took Mary and Joseph on fossil-hunting expeditions. Mary continued to support herself through fossil hunting as she grew older. 

While scouring the beach in early December 1823, she came upon a fossilized skull that was like nothing she’d seen before. The majority of the skulls she had previously found belonged to Icthyosaurs; they were long and narrow, a bit like the heads of dolphins or crocodiles.

This skull, on the other hand, was small, beady-eyed, and had a mouthful of strange, needle-shaped teeth. Calling upon nearby villagers for assistance, Anning carefully unearthed the rest of the mystery creature’s body. Attached to a stout torso and broad pelvis were four flippers and a diminutive tail. The long neck was the most peculiar feature, however, accounting for nearly half of the 9-foot creature’s length.

She wrote to a colleague describing her discovery (see a page from her letter below) and her place in the scientific community was sealed, though many of her peers were initially skeptical. In fact, at a Geological Society of London meeting the following year, Reverend William Conybeare (a fellow paleontologist) stole the show with a well-received presentation on the nearly complete Plesiosaurus from Lyme Regis. He also published a paper featuring detailed original illustrations of the specimen. However, neither his presentation nor his paper mentioned Anning and he initially stole credit for the discovery.

Over time, Anning’s discoveries became key pieces of evidence for extinction. Her work also became well known in literary circles as well; Charles Dickens wrote of his admiration of her 18 years after her passing. Legend has it the children’s rhyme, “She Sells Seashells”, is also a tribute to her work:

She sells seashells on the sea shore.
The shells she sells are seashells, I’m sure.
And if she sells seashells on the sea shore,
Then I’m sure she sells seashore shells.

Anning died from breast cancer at the age of 47 on the 9th of March 1847. Admirably, when the Geologic Society learned of her diagnosis, its members began raising money to cover her medical expenses. Later, her funeral was paid for by the society which also financed a stained-glass window dedicated to her memory that now sits at St. Michael’s Parish Church in Lyme Regis.

Bring it Home – Lessons from Mary Anning

Nature journals are as valuable a learning tool today as they were in earlier centuries. The image below comes from a letter written in 1823 by Mary Anning describing her discovery of what would be identified as a Plesiosaurus. Mary Anning Plesiosaurus

Visit a local natural history museum and create a nature journal entry on one of the specimens on display. Inquire with the staff about the process and care involved in curating skeletal specimens.

Participate in a fossil walk.

Begin your own collection of fossils.

If possible, visit the Natural History Museum in London or the museum in Lyme Regis.  We recently had this opportunity when we traveled to England in 2017. Here you can learn more about the pioneering work of Mary Anning and see some of the most complete fossils of prehistoric sea animals, including ichthyosaurs and plesiosaurs. Plus, look out for the skeleton cast of the giant ground sloth, a land mammal often mistaken for a dinosaur.

Novelist Tracy Chevalier (author of The Girl with the Pearl Earring) has made a career of bringing history to life. Chevalier’s newest novel is called Remarkable Creatures centers around the life of Mary Anning. The novel introduces readers to Mary’s unlikely champion, Elizabeth Philpot, a middle-class woman who shares her passion for scouring the beaches. Their relationship strikes a delicate balance between fierce loyalty, mutual appreciation, and barely suppressed envy, but ultimately turns out to be their greatest asset. Based on real characters, I found the story interesting. I was moved to realize just how difficult it must have been to persevere with the social obstacles she encountered in her time.

10 Nature Discoveries on the Sandy Shore

The sandy shore dominates much of the open coastline of the Pacific Northwest, stretching uninterrupted for miles in many regions. These dynamic habitats represent the most physically controlled of all the nearshore marine habitats and are considered one of the hardest places to live. As such, understanding the nature of the habitat and the animals that live there is important.image of a teen walking on a sandy beach with text overlay "Nature Discoveries on the Sandy Shore: 10 Activities for Teens" @EvaVarga.net

Sandy beaches are in a constant state of change and motion. Animals on exposed sandy beaches must protect themselves from shifting, abrasive sand and heavy surf.

Hands-on Activities to Explore the Sandy Shore

My family and I have spent much time exploring the ecology of the sandy shore and immersing ourselves in nature discoveries. There are many opportunities to learn more about this environment. Here are few ideas to help you get started:

Collect samples of beach sand from different beaches and classify each into coarse, medium, and fine sand. Can you see evidence of animal life in the samples?

Send the kids on an scavenger hunt of the intertidal invertebrates – note that many of these are not residents of the shifting sands of the sandy shore but are found clinging to the rocks and along the margins shoreline.

Be ready for the unexpected; you never know what you might discover while walking along the sandy beach like these Rare, Bizarre Creatures from the Deep. Finding an animal or plant that is unfamiliar to you is a great opportunity to seek out the answer. Can you find it in a guidebook? Do others know? Consider reaching out to local experts (remember to bring a photo) for help. Resource specialists at Fish & Wildlife offices are eager to answer questions and share their knowledge with the public.

getting started in 5 exercisesBegin a nature journal and showcase your discoveries. Here’s a peak at one of my son’s earliest entries, The Elusive Brittle Star: An Hawai’ian Nature Study. Need help to get started? Check out my tutorial, Keeping a Nature Journal: Getting Started in 5 Exercises.

You may also be interested in a college level course, Nature Journaling in the Classroom. The course is offered through the Heritage Institute and optional, university credit is available.

Do a little research to learn more about the animals that live in the surf-swept coastline. How are they adapted to life in this physically demanding habitat? Compare and contrast the means of mobility of two animals commonly seen on California’s Central Coast: Ventura Beach: the Pacific Mole Crab and By-the-Wind Sailor. Make a list of the adaptations you have observed.

image of two marine invertebrates: By the Wind Sailor (jellyfish) and Pacific Mole CrabChallenge your kids to design their own plant or animal specially equipped to survive on the sandy shore. Draw a picture of the organism or build a 3D model. Tell how it is adapted to life here.

Take Action to Protect the Sandy Shore

As a life long resident of the Oregon coast, the condition of our local beaches and ecosystems is very important to me. The idea of citizen science or “public participation in scientific research,” has also always been a passion of mine. Here are a few ideas in hopes of inspiring your family to get involved:

Take part in aBioBlitz –  an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time. We took part in 2014 but they happen annually.

image collage of a young girl upcycling plastics to create artOrganize a family beach clean-up and do your part to spread the word about the dangers of single-use plastics like Washed Ashore

Feeling inspired? Collect plastic bottle caps to create a colorful mural and donate it to a local non-profit.

Just for fun, create a Labyrinth on the Beach and invite others to join you. Encourage participants to make a pledge to do their part to make a difference.

Guidebooks to the Sandy Shore & Other Habitats

The Beachcomber’s Guide to Marine Life in the Pacific Northwest by Thomas M. Niesen is one of my favorite marine ecology guides.  Each page is features incredible hand illustrations (by artist David Wood) that really capture the organism with a detailed simplicity.  Additionally, black and white images (though some are a little dark) and 16 pages of color photographs in the center of the book provide  excellent coverage.

Though this is not a pocket guide, Dr. Niesen writes in very clear language to help you identify what you are looking at, learn about its life habits, as well as its habitat. Organized with an emphasis on habitats and arrangement by type of organism within each habitat (sandy beach, estuaries, rocky intertidal, open ocean, etc.) is extremely helpful. Niesen also goes into great detail about the different tidal zones and the particular creatures you will find in each zone.

The ABCs of High School Electives: Translating Passions on Transcripts

As the academic year comes to a close, you may be thinking of nothing more than your summer bucket list. Many students however, like my daughter, have their eyes set on pursuing opportunities that can better prepare them for their career choice or expand their extracurricular experiences.

image of teen girl giving an oral presentation or speech

This past summer my daughter attended a week-long engineering camp at the university. This opportunity not only provided her with insight into her field of interest but also connected her to key personnel in the department. She emerged with a greater understanding of the skills she will need to succeed in her field. She also collaborated with another teen on an engineering project and gave a presentation at the conclusion of the course.

Summer camps like the one I described and short courses in art or sailing provide youth with hours that can be used for elective credits. Unlike required courses, electives are classes the student chooses based on her interests. It is the perfect way to customize a child’s education.

ABCs of High School Electives

While most high schools offer electives that cover a wide variety of topics, homeschoolers have the opportunity to craft a transcript that is unique and the most reflective of a student’s interests and future career goals.

This past year for example, my daughter has been actively involved in the Debate Club at the local community college. While it is an informal group (they haven’t competed against other schools), they are engaged in forensic experiences. The hours she attends and the research she invests in preparing her speeches can be applied to her transcript.

The possibilities are endless. Here are just a few ideas to get you started:

A – Art & Graphic Design, Aeronautics, or Architecture

B – Birding (Ornithology) 

C – Culinary Arts

D – Drama, Drones (Small Unmanned Aircraft Systems)

E – Electronics 

F – Forensic Science

G – Game Design (Coding)

H – Homemaking

I – Interior Design

J – Journalism

K – Kinesiology (Sports Science)

L – Languages

M – Music (Performance & Theory)

N – Naturopathy, Nursing, or Nature Studies

O – Oceanography (Marine Science)

P – Psychology

Q – Quilting (Fiber Arts)

R – Robotics

S – Sociology

T – Toastmasters (Public Speaking and/or Debate)

U – Urban Studies

V – Venturing (Scouting)

W – Web Design 

X – Xeriscaping 

Y – Yearbook 

Z – Zoology

It would be impossible for any single school – public or private – to offer every elective on this list; there are simply too many. Schools are forced to choose which electives to offer based on a number of factors including location, student population, resources available, teacher expertise, and student interest. Homeschools, on the other hand, are not restricted by these factors.

Translating Elective Hours on the Transcript

Translating the hours a child has invested in a particular area can be done with ease. Simply keep an activity log as documentation of the hours invested. Click on the image below to download a FREE copy for yourself.image of an activity log used to track hours of instruction

In Oregon, 1 high school trimester is equal to 1 high school credit hour. This translates to approximately 55 hours of seat time/instruction. Thus, the 61 hours my daughter volunteered at the art museum last summer earned her 1 trimester credit.

These hours can be accumulated by watching instructional videos, TED talks, attending local seminars, reading informative texts, taking a specialized course (either in person or online), or any myriad of things related to the field of interest.

Use the course descriptions provided by local schools as a guide as you write your own. Keep in mind that electives can have different names depending on the school offering them, even if they cover essentially the same topic (for example, a culinary arts class could also be called cooking, foods, or something similar).

On a related note, forensics has long meant the art of speechmaking and oral presentation. Debate clubs, on the other hand, involve students in researching a pre-selected topic and then trying to convince people of their position. It’s a cousin of forensics but not the same thing.

To add to the confusion, Forensics Clubs and courses in Forensic Science are popping up in many modern schools, inspired by popular television shows. Using an optional course description can help to alleviate any confusion.

A Guided Tide Pool Hike with a Master Naturalist

Having grown up on the Oregon coast, I have been fascinated by marine animals since I was a young girl. I spent many long summer days exploring the tide pool and estuarine habitats in my neighborhood.

A naturalist at heart, I have inundated myself in ecology and natural sciences ever since, completing the coursework to become an Oregon Coast Master Naturalist a few years ago. Today, I am delighted to take you on a guided tide pool “hike” to one of the hidden gems of the Oregon seashore.

Cape Arago State Park

The tide pools at Cape Arago are incomparable. Here, you’ll find easy access to both the North and South Coves of Cape Arago. Tucked away below the cliffs, a short walk along the steep trails will take you to a secluded cove where tide pools and fossils can be found.

The south trail leads to tide pools teaming with diverse sea life. The north trail lets visitors view offshore colonies of seals and sea lions (however, the trail is closed from March – June to protect the seal pups during birthing season). Visitors to the area can also enjoy whale watching, crabbing, fishing, and scuba diving.

Nearby, there are two additional state parks: Sunset Bay (a sandy beach protected by towering sea cliffs – perfect for sunbathing and swimming) and Shore Acres (a lushly planted garden perched on rugged sandstone cliffs high above the ocean – once the famed estate of Louis Simpson).

Let’s now begin our guided hike of the south cove at Cape Arago.

Guided Tide Pool Hike

Upon hiking down the south trail you will first come to a small sandy beach. There is often driftwood and marine debris along the high tide line, pushed up against the base of the cliff atop the rocks and small boulders.

Purple Olive Snails

image of purple olive snails buried in the sand. Text overlay reads A Guided Tide Pool Hike with a Master Naturalist @EvaVarga.netAs you walk nearer the shoreline to the waters edge, you may see tiny little bumps in the sand. Olivella biplicata, commonly known as purple dwarf olive snails, burrow themselves in sand, leaving a plowed trail behind it. The foot is wedge shaped to facilitate plowing.

While burrowing it raises its long siphon up through the sand as a snorkel. They can be found nearshore on fairly quiet, protected beaches and farther offshore on more exposed beaches. Their predators include the seastarsoctopus, moon snails, and gulls. Most active at night, often move up and down the beach with the tide. Omnivorous, they eat kelp blades and both live and dead animal material.

Take a closer look, however. Some of these snails are not like the other.

Hermit Crabs

The snail shell at the top is inhabited by a hermit crab. There are more than 1000 species of hermit crabs -decapod crustaceans that possess an asymmetrical abdomen that is concealed in a scavenged mollusc shell which it carries around. As the hermit crab grows, it will seek out a larger shell.

Young boy holding a purple shore crab with text A Guided Tide Pool Hike with a Master Naturalist @EvaVarga.netShore Crabs

Hermits are not the only crabs you’ll observe in the tide pools. Crawling about between rock crevices and amongst the blades of kelp and marine algae are a diverse number of small crabs, each with its own distinguishing characteristics.

  • Purple shore crabs – Hemigrapsis nudus (pictured above) reaches sizes of approximately 4.0–5.6 cm and is generally dark purple in color, although it may be olive green or red, with white or cream markings. The color of the legs matches the color of the carapace but the white-tipped claws are a lighter color with purple or red spots. These markings distinguish it from the similar…
  • Lined shore crabs – Pachygrapsus crassipes, whose chelipeds lack spots.
  • Oregon shore crab – Hemigrapsis oregonensis is a similar species with setae or small hairs on its legs, a distinguishing characteristic the other two lack
  • Porcelain crabs – a flat, round body (perfectly adapted to life between rocks) with two large front claws, these delicate crabs readily lose limbs when attacked, and use their large claws for maintaining territories.

Blood star - a red, five armed sea star common on the Oregon coastSea Stars

No matter the depth or the substrate, these spiny skinned invertebrates are among the most successful marine creatures inhabiting the coast. The abundance and number of stars found along the west coast of North America is without equal in the world. I highlight just one in my post today.

Henricia leviuscula, the Pacific blood star, feeds mainly on sponges. It is fairly stiff with only small papulae (skin gills) and tube feet. It seems to rely much more on seawater uptake through the madreporite (a series of seawater-filled ducts that function in locomotion, feeding, and respiration) than do other sea stars of comparable size.

The gumboot chiton, Cryptochiton stelleri, can be found clinging to rocks, moving slowly in search of its diet of algae which it scrapes off of rocks with its rasp-like retractable radula, covered with rows of magnetite-tipped teeth.

Unlike some other chiton species, C. stelleri has well-developed ctenidia (gills) in the groove beside the foot (pictured above). A commensal polychaete worm can sometimes be found here, as can the pea crab, Opisthopus transversus.

green sea anemone with embedded image of an aggregating anemone Sea Anemones

There are many anemones in the tide pools of the Pacific Northwest. One of the most common is the green anemone, Anthopleura xanthogrammica. Anthopleura is not just one species, however. Hidden within its tissues is an algae.

In this symbiotic relationship, the algae gain protection from snails and other grazers and don’t have to compete for living space, while the anemones gain extra nourishment from the algae in their guts. Contrary to popular opinion, this anemone’s green color is produced by the animal itself, not the algae that it eats.

Another fascinating anemone is the aggregating anemone (pictured in the embedded photo above), Anthopleura elegantissima, the most abundant anemone species found on rocky shores along the Pacific coast.

Aggregating anemones can rapidly clone themselves. If buried by shifting sands, they can survive for more than three months.

Tide Pool Guidebook 

You may not have the opportunity to explore a tide pool with a naturalist when you visit the Pacific Northwest Coast. In this case, you will want to find a guidebook or two to help you identify the diverse wildlife you will encounter.

One of the books we have at the marine life center that our visitors enjoy perusing when they have questions is The Beachcomber’s Guide to Seashore Life in the Pacific Northwest by J. Duane Sept. It was revised in 2009, it is beautifully illustrated and is a great guide to identifying the most common intertidal animals and plants of British Columbia, Washington, and Oregon.

The size is perfect to toss into your day pack if you wish to look up a specimen on your trek. It is written with the beachcomber in mind so while it does not feature every species, it is an excellent starting point for the more general specimens you may encounter.

While here, you may also be interested in Oregon Coast Quests – fun, educational, and clue directed hunts specific to the Oregon Coast.
