lemudillo said to look for the fuzzy green algae. She wasn't wrong. I found a handful of shallow pools loaded with this algae up on a rather exposed ridge, and lo and behold, they held a bunch of this lovely little sacoglossan, Aplysiopsis enteromorphae.
I see these every now and then. Much like giant keyhole limpets, they have teeny tiny little shells that they wear like a small hat.
Saw more peanut worms than I think I ever have before.
About 1 cm long, observed at Scott Creek State Beach near Santa Cruz, CA, in the rock intertidal.
Like so many things, it would not stay still.
Found this little octo clinging to the side of a rock.
