In the dense plankton bloom, nudibranchs were strangely underrepresented.
This is the British Columbia classic, a men’s shoe size 10 nudibranch, Tochuina tetraquetra.
It's also known as the orange-peel nudi.
Another B.C. classic, Dirona albolineata.
This color variation is also Dendronotus albus. Until recently, it had been classified as Dendronotus diversicolor.
Could this tiny one be a Dendronotus albus juvenile?
Dendronotus iris from a white-out plankton bloom at Hoodie-Nudi Bay.
Hermissenda crassicornis color variation
In Palos Verdes, we saw oodles of both species of Corambe eggs as well as dozens of adults, but inexplicably we never caught them mating. I was pleased to find zesty clusters of mating Corambe steinbergae.
Geitodoris heathi looks quite different from ones we find here. ID thanks to Dr. Jeff Goddard, who wonders if a genetic analysis might eventually show these to be a different species.
Geitodoris heathi with two different yellow sponges.
The sponge at the bottom is the yellow encrusting sponge or sulphur sponge, Myxilla lacunosa, while the one at the top is the bristly ¬¬¬¬yellow sponge; note the fibers. There is uncertainty with respect to classification of that sponge.
Tritonia festiva and a fishy friend that’s consuming something.
Here’s some behavior. Checkered hairy snails, , consume waste products from the serpulid tube worm, so I presume this snail has positioned itself thus.
Blue topsnail, Calliostoma ligatum
The Oregon Triton, Fusitriton oregonensis, is the state seashell of Oregon.
Blue-line Chiton, Tonicella undocaerulea
Basket Star, Gorgonocephalus eucnemis
Sea Grape, Derbesia marina
