I have absolutely no idea what this thing is. I found several of them lying in the sand near tide pools in Venice, CA. They were firm to the touch and less slimy than you might expect. I think they were colonies of something which had fully covered the surface of a rock or shell, which would explain the irregular shape. Can anyone help me out with ID’ing these??
