Marsenina stearnsii is a species of small slug-like sea snail, a marine gastropod mollusc in the subfamily Lamellariinae of the family Velutinidae.

This white slug-like snail is known from Alaska [3] and central California. [4] It can be found in the rocky intertidal, often in association with the ascidian Trididemnum opacum . [4] [5] It is relatively rare, found in the low rocky intertidal, usually under rocks on the ascidian Trididemnem opacum which it matches in color and pattern and upon which it preys. [6]

Diodora aspera, also known as the rough keyhole limpet, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets. Although similar in appearance to a common limpet, it has a hole near the apex of its shell, and is only distantly related. It often has a scaled polychaete worm Arctonoe vittata living inside its shell as a commensal. In the event that it is attacked by a starfish, it extends flaps of mantle to defend itself, and the worm also helps drive the predator away.
