I've been working on some photo organization, but here's a little Orange Cup Coral for you — Balanophyllia elegans, photographed in Bodega Harbor.

Plume de mer?
Close-up of the gill plume of the nudibranch sometimes known as a Sea Lemon (Peltodoris nobilis). Note the extensive branching to increase surface area for respiration.
Evidence suggests that nudibranchs evolved from gastropod ancestors that
lost their coiled shell and original internal gills. Dorid nudibranchs
like this one secondarily evolved an external gill plume for
respiration.

Above, note how well the octopus blends in with the background, matching the surrounding colors and textures.
Below, a closer view from the side next to the sea anemone:

Spindrift and light
10-foot swell + 15-second wave period + an offshore breeze = a setup for spindrift!
A few wave photos from this morning (12 January 2026).
