-	Cancellaria cooperi comes up underneath a California torpedo ray, and sucks its blood, often with the ray not seeming to respond.	-
Bursa californica (or California frog snail) is a carnivorous snail, feeding on polychaetes and other prey. To reproduce, a female lays egg capsules in a half a clam shell and stays on the brood until they hatch as free swimming feeding veliger larvae. Each of the hundreds of egg capsule here has hundreds of embryos, only most of these had already hatched. The snail is a member of Bursidae (Littorinimorpha), which is a diverse group of snails in the tropics and in the southern hemisphere.	-	-
