The picture is unclear, but I observed these two seahares intertwined. I cannot be sure if they were fighting or mating.
I found this species on a flat rock along the shore of TPSNP. It was in a tide pool on top of that rock.
I observed this species washed up on the shore at the bottom of Sunset Cliffs, CA. After washing most of the sand off (and taking a picture), I put it back into the ocean.
Found munching on some red algae in the tidepool shallows
One of two dead at the high tide line. Oozed purple goo when I tried to move it.
