Wondering what kind of animal this vertebrae is from. Found washed up on a beach.

Unsure of species.

This observation is for the larger red one. The animal was brought onto the Wet Deck of the Sea Center for observation.

Associated with a warty sea cucumber

Eggs on driftwood - @jeffgoddard do you have any thoughts on these?

Found in the mantle of Aplysia californica
@jeffgoddard do you know these? I wish I'd taken a bit more time to photograph them, the patterns are beautiful
@skatingflamingo check those sea hares!

Egg mass approx. 5 mm across.

Extremely abundant at this location and date. Some of it looked strange on the surface, as shown in first two photos. In the first photo, Scopalina nausicae is top left and lower right.

A broken snail shell found on the ground among some rocks. Photographed on my middle finger for a size reference.

ID based on iNaturalist's suggestion.

Yellow encrusting bryozoan

Hoping to identify the larger yellowish structures, not the smaller white ones. Assuming they are different species.

Not sure

What is this little thing with bristles / hairs? Is it a part of a crab? It looked like its own independent organism. This was seen in a holdfast.
