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…

Dodecaceria, Cropped

This mound is home to a colony of marine worms, Dodecaceria, probably D. fewkesi. Here, the worms have retreated, it being low tide, into their calcareous tubes. Their tubes are embedded in a matrix of cemented sand particles. When the tide returns, they’ll poke their tentacled heads out to feed. A version of the photograph…

Revisiting a Landmark

Below, is the first photograph I took of what is now one of my favorite northern Oregon landmarks. I say landmark, as far as I know, it’s not a landmark for anyone but me. It isn’t a single rock, it’s a pair. Allies rising up together on the lowest reach. Accounting for tides and surf…

A Simple Pleasure From the Shore

Mazzaella splendens is one of those red seaweeds known for the looks it throws your way. Its iridescence isn’t a given, but when things fall into place, rainbow leaf, as it is sometimes known, lights up the low intertidal. Cut off from the shore, I’m grateful for simple pleasures past. Simplicity Addendum: There couldn’t be…
