Research study 1

photograph of moon-snail shell with operculum visibleThere are no studies specifically relating to predators and defenses in west-coast moon snails. Neverita lewisii crawls about openly on the sand and, in intertidal locations, is sometimes exposed to air or at least is shallow enough to be visible and photograph of a moon snail partially withdrawn into its shell lying alongside an egg collar, perhaps its ownaccessible to birds. The flesh is plump and seemingly tasty to fishes, so if fishes avoid moon snails as prey, the liklihood is that the flesh is toxic or otherwise unpalatable. The shell is strong and protected by a proteinaceous operculum (see photograph of museum specimen on Right), but moon snails in nature are rarely observed to be withdrawn completely in their shells. Clearly, research on the subject is needed.

its operculum, but some fleshy parts are in the way 0.3X
