@ 35fsw

Alive and moving. On the edge of the shore at a negative low tide.

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.
