Ficus subintermedia, from here.

Belongs within: Littorinimorpha.

The Ficidae, fig shells, are a small family of tropical shallow-water or abyssal marine gastropods that take their name from the roughly fig-shaped appearance of their shells. Fig shells are predators of echinoderms.

Characteristics (from Wilson & Gillett 1971): Thin shell; spire low, final whorl inflated with wide aperture, anterior canal long, tapered and curved. Operculum absent. Head small, siphon long. Mantle lobes spread over most of shell.
