Tidepool Treat: The SchizymeniaKatharina Connection

The low tides of late summer brought me a tidepool treat. I’d read about a connection between a red seaweed called slimy leaf, Schizymenia pacifica, and the Katy chiton, Katharina tunicata, but hadn’t seen it myself. I had seen Katy chitons decked out with various seaweed and animal hitchhikers, but I did not recall slimy leaf among them. By…

Bringing You Along

Just memories now, of a beach walk, August 19, 2020 6:17 am: Accepting an intertidal invitation. 7:02 am: Touching base with an old friend, a study in zonation. 7:58 am: A pause to take in morning sunlight on exposed surfgrass. 8:19 am: A fortunate turn of my gaze, just in time to discover sunbeams penetrating…

Off to the Shore for a Symmetry Beach Party

Welcome to my small celebration of symmetry. This beach party’s a renewal of kinship with animals we share symmetry with and a reminder that symmetry varies in ways worth appreciating. An in-depth survey of symmetry would expose developmental and evolutionary mysteries better left to zoology and comparative anatomy courses. Instead, let’s head to the shore,…

Accentuating a Flatfish and a Limpet with Negative Space

This little flatfish, one of those pesky pleuronectids, the righteye flounders, was just a babe, washed up as so much sea wrack when I noticed its perky eyeballs protruding from the smooth, featureless surface of a sea of swash zone sand. The experts I consulted believe it’s a juvenile starry flounder, or maybe a curlfin…

The Crowded Rocky Intertidal Bursting with Life

Surf swept rocky northeastern Pacific shores host marvelous biological diversity and abundance. A good place to witness the profusion is up close, on the dead level with a barnacle. Surrounded by neighbors, a giant barnacle, Balanus nubilus, entertains tenants of its own. Stepping back, viewing the world from the lowermost horizon of the mussel bed…

Macro Monday: Pollicipes polymerus

When it comes to intertidal close ups Pollicipes are agreeable subjects. They won’t much change their demeanor if, to get things right, you need to nestle in among them. Gooseneck barnacles, Pollicipes polymerus, stick to surf-swept shores. They stand out in the the mussels beds.

Before I share what I’ve been up I want to acknowledge Covid-related suffering everywhere and express my gratitude that I have a job that keeps me safe, and that no one close to me has contracted the disease.

Missed Opportunities with Littorina sitkana and Gloiopeltis furcata

I’ve surprised myself twice recently by unexpectedly noticing species I’ve never seen in the wild in my photographs featuring other species. The periwinkle below, the little striped snail, escaped my attention while I engaged in a four-photograph sequence featuring the limpets. The little snail is Littorina sitkana, the Sitka periwinkle. Who knew a snail could…

Quiet Moments From the High Intertidal

Among invertebrate inhabitants of the high intertidal, activity, for some, grinds to a halt when things dry out. Clamped down against a vertical wall with shells for protection, waiting out low tide won’t challenge these limpets and barnacles. It doesn’t hurt that they’ve settled on the shady side. A periwinkle made it just so far…
