The name “tun” refers to the snails’ shell shape which resembles wine casks known as “tuns”. While the shells are thin, they are also strong. There is no operculum. They are found in all tropical seas, where they inhabit sandy areas. During the day, they bury themselves in the substrate, emerging at night to feed on echinoderms, crustaceans, and bivalves. Some larger species also capture fish, using their expandable proboscis to swallow them whole. Females lay rows of eggs that become free-swimming larvae for several months before settling to the bottom.
