A clamshell, held in my hand, with the open front facing us. The shell is completely covered, inside and out, with barnacles, which prevent the shell from either opening or closing. In the open space can be seen, left to right, a white and cream trophon snail, a mud snail with three or four barnacles on its shell, and then a leg, two chelipeds and another leg of a hermit. Next is another shell which may be holding another hermit. Behind and below these are hints of other beasties, all jammed together in the dark.
The hermit is a Grainy-Hand; the olive-green cheliped has pale blue dots, and if you look closely, you can see his orange antennae in the shadows.
(There are actually three Grainy-hand hermits here, but only one can be seen clearly. Also present; more snails, many different worms, tunicates. The clamshell was highly desirable housing.)
A couple of blades of dead eelgrass drape over the clamshell.
Background; water over a sandy beach.
