Focusing on the Details: Thatched Barnacles

Dropping down on a new reach of shore is disorienting enough that it takes a while to shake it off. It’s not unusual to arrive with questions about how and where to proceed. (Most of these, with a bit of planning, can be answered in advance). Once I’m on a new shore, all preparation seems…

On the Rocks: Now and Then

It’s the setting, height, and shape that make the rock below an intertidal superstar. This surf zone heavy-hitter sits in an intertidal sweet spot where accessibility and rarely exposed lower reaches find the optimal balance. It’s a leviathan tall enough to support all the intertidal zones, and its steep broad faces impart visibility to the…

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…

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…
