~tidepool immersion~ within and just outside

This is a bird. I found three options on a blog of what it might be. To my eye, it looks most like the surfbird, but based on the description of rock sandpipers being solitary and quiet, that seems like a likely choice. It also resembles (to a person who looks at fish all day) the black turnstone, so I am not ruling that out as an id, either.

There was quite a breeze, and I loved the way the outer tidepools divided between the textures of the water within and just outside.

The find of the day was a dead octopus! I have never seed a live octopus in a tidepool, and while that would have been cooler, this was pretty remarkable to see. I stared at the scene for quite a while as quite a few hermit crabs crawled around the suckers. The large red sea urchin appeared to be quite interested in octopus meat as well.

I think the anemone pictured above is a painted anemone (Urticina grebelnyi). Below is our very common giant green anemone.

Kodiak July 2023. I got to see humpback whales right away, day one on the water. And also days two, four, six, and seven. Whale wealth!

 

Kodiak day two on the water brought even more whale wealth than day one. Humpbacks and killer whales. It was gratifying to hear “we’ve only ever seen them one other time in eighteen years of this survey.” I can’t take much credit but I did put in a special request.

Not pictured but still helping fill my Kodiak wildlife bingo card: Dall’s porpoise, sea lion, harbor seal, and river otter, golden eagle. Not to mention all the rest of the fish, but we won’t say much about the fish, for they are data.
Did you know that one of the collective nouns for puffins is “an improbability of puffins?” I was delighted with not just pairs, but whole rafts, improbabilities, of puffins.
I’ll be back in August to what is quickly becoming another favorite place of mine on Earth.

banner day

This kind human is a sophomore. He spent our labor day hike dispersing dandelion seeds because, “every living thing deserves a chance to grow.” I made a wish on each seed, in similar words, but my wishes were all about him.

Also, today we sign closing papers to buy the dragon house. A long-held dream comes true.

 

Honorable mentions:

I am halfway through semester three of my program, and still loving every 4am writing session. On a sunny day back in January, I typed one of my essays on Great Grandma Rew’s typewriter and submitted it to a zine called Selkie, and I recently received word that they’ve published it! I will share how to get copies when they become available. My first published essay, hurray! In a zine named for mythical females who zip in and out of sea-suits to live in both realms, on the theme of “disobedience.” Sounds about right!

I started my permanent job in July. I’ve filled out what could be the last round of new hire paperwork, for the last set of changing benefits, and the waves of relief are still washing over me, and I expect that will keep going for some time. Three pay periods in, I went to Kodiak, Alaska, for field work. A new place to fall in love with. (They have otters there!!!)

tidepool immersion~blue inside

 

(The photo above is from a different beach I visited on a grayer, less photogenic day, save for these colorful anemones.

All that follow are from a single tidepooling trip.)

 

On my recent tidepool walk, I found a fish lying on the sand. A large sculpin? I picked it up to take a picture (as one does). In my hand, its body shifted so that its mouth dropped open and I gazed into a gaping chasm of blue! Its mouth is blue?! Simultaneously, its opercula opened, closed, gasping. It was still alive!

 

I snapped quick photos and rushed it into the water. It lay on the bottom, letting water pour across its gills, brown lumpy body camouflaging its secret bright interior. At home, I looked it up: a cabezon, part of the true sculpin family, a rocky intertidal dweller who feeds on crabs, fish, and mollusks. In its blue inner realm – not just mouth, but also flesh and internal organs – tiny abalone shells are said to become brightly polished in its digestive acids. The cabezon spawns on rocks, where its eggs, poisonous for consumption, can disperse up to 200 miles from shore, drifting as embryos divide, develop, hatch into wiggling larvae, absorb their yolk sacs. Arriving back in their tidepool spawning ground as fry, they hunt and grow into adults who lurk in the kelp beds.

 

I walked to the farthest extent of the beach one can access, and then only on these lowest low tides. Actually, I stopped short of the farthest tippy tidepool at the end once I spotted hauled out seals, and ceased approaching. Took zoom lens photos of baby seals raising their heads and rear flippers like they were rehearsing their swim, strengthening their core muscles.

Discodoris sighting! aka Diaulula sandiegensis from family Discodorididae

I chose fishing line as my genre of litter to collect on this day, filled my pockets.  Stepped across a vein of something agatized or fossilized. Made by pressure, revealed by water, without having to dig.  The smooth light gray rock erodes pockets and dimples. The small black cobbles collect inside. On the farthest stretch, the crabs are less accustomed to having to hide from hikers, and they plop and tumble into tidepools, scuttle and skitter under eelgrass clumps.

 

Otter is the name of the beach I wandered, though the last known individual sea otter swimming in Oregon waters was shot off Newport in 1907. Locally extinct ever since, they no longer exert control over sea urchins, which can overgraze the kelp holding down the base of this ecosystem.

Other species help in the role of maintaining kelp forests, though none to the extent that otters once did. I leaned over every edge of every farthest shelf of rock on this day, hoping and wishing to see a sunflower star.

(Like the one Quinn is touching here in 2010.)

(Or this pair from 2011.)

But sunflower stars have reached critically endangered status as of December 2020, failing to make a comeback from sea star wasting disease. Locally extinct now in the southern part of its range (zero Mexico or California sightings since 2018), sightings in Oregon are now vanishingly rare. I have not been able to find one.

I did see a leather star, though, between meals of anemones. A number of purple and ochre sea stars wrapped around mussels. Some species are making a halting comeback, others not. They will pull on the threads that connect them to other species until a new equilibrium is reached.

 

Maybe it’s because I’ve just finished reading Into Great Silence, a memoir written by a woman who studied the Chugach transient orca pod in Prince William Sound, a diminishing group that has not reproduced since the Exxon Valdez emptied oil into the sound in 1989. There are now just seven individuals. Maybe it’s because the author, Eva Saulitis, included a quote from the poem The Last One by W.S. Merwin, so I read the rest of the poem. I think a lot about these last ones, the impossibly lonely condition of being a last one, that so many species are facing. And then the one is gone, and there are none. Maybe it’s because I felt like I discovered a kindred spirit in Eva as I read her book, and know that she, too, is gone. Or maybe I’m a cabezon. I’m just a little blue on the inside, too.

 

 

tidepool immersion ~ pink moon low tide

 

Last week we enjoyed a very low minus tide series courtesy of the full, pink, willow moon. It was just setting when I arrived at my destination.

I met this hummingbird while tidepooling – a bit unusual for a tidepooling find!

 

I don’t often get photos of feather duster worms, so this was a special treat. Apparently they have giant nerve fibers that help them retract very quickly when disturbed, to avoid getting eaten. They also have light-sensitive eyespots on their gills so they can sense a predator by its shadow passing overhead!

As the sun started coming up over the ridge, the colors became so much more vibrant.

tidepool immersion ~ disco doris

I have been thinking about posting some longer photo-heavy posts of some of my personal nature walks to share so that others can vicariously go along for the hike. These photos are from a tidepool walk on one of the last morning negative low tides of the season (y’all remember how I made my own college course on how the tides work back in January, right?) and I was having trouble choosing which photos would go into a rainbow monday post… so I decided to make them their very own post… virtual nature walk #1 tidepool immersion!

new nudi! ring-spotted doris whose scientific name Discodoris, beats the common name hands down. Disco Doris!

I am not sure what species this egg case belongs to… I’m thinking some kind of mollusk/snail?

 

~summer shorts~ star ecology

A disease outbreak erased sea stars almost completely from the tidepools of our coasts in 2013. I see them in greater numbers than I have in years, but still with telltale symptoms of the devastation they’ve suffered.

Sea star wasting disease is still poorly understood, and having worked in disease ecology professionally, I know this is not for lack of attempts made to understand. It is a very tricky branch of biology to study. Sea star larvae go through a dispersed pelagic phase where maybe their socially distant selves manage to stay disease free.

As the new recruits settle back into the intertidal, some of them have managed to grow to maturity at least long enough to spawn for themselves, but most are still showing telltale signs of infection with this disease some scientists believe may be caused by a virus. The disease persists, and for now sea stars, too, persist. It will remain to be seen how the population will respond longer term, and what effects their prolonged absence will have on the other organisms in the intertidal community. The invisible, inextricable linkages connecting members of an ecosystem sometimes reveal themselves when the system is under strain.

I have spent a few early morning tidepool rambles on a few different beaches I love, my own very small emergence into the world in a low-covid-risk manner. I make a point to watch for and photo-document sea stars now whenever I am out for one of my beach walks during low tides. For several years I saw almost none, but slowly an increase is becoming perceptible.

I lingered a last few minutes on one beach, and a hermit crab captured my attention, tucked into a former snail’s abode frosted with pink icing bryozoans. I watched and watched, and it slowly, slowly, emerged. Our return to the world feels comparably slow. I think we will be hermits for longer than is comfortable, and face choices about how we minimize our in-person interactions with the general public so we can reimagine the in-person interactions we don’t want to continue to have to live without. Not the triumphant takeover of the world as we knew it, but a halting, complicated return, much like the quiet, incremental return of the sea stars.
