Egg mass, laid in a glass dish, was 13 mm in total diameter.
Egg mass; adults were found nearby.
One of two found, and the only nudibranchs I found in about one hour of searching this site on a -0.5' tide. Most of the pools and channels were scoured by the abundant cobbles present, and at a site like this, it's probably still too early in the season to find many nudibranchs.
Two of the 19 I found this morning. Both found as shown, hunkered down and likely feeding on hydroids, two species of which are visible in the 2nd image.
2nd image shows a juvenile as found, next to Dendrobeania lichenoides under a small ledge.
Found two individuals this morning at Scott Creek.
I found 45 individuals of this species in 2.5 hours of searching this morning.
Form A; only specimen of this species three of us found this morning.
Juvenile next to its sponge prey (likely Halichondria panicea) underneath a small ledge.
Found by Jules Wyman; one of two that three of us found this morning.
We found about 20 adults feeding on Cladophora columbiana in high intertidal pools.
One of eight we observed this morning.
