Moon Snail

These snails are responsible for the curious sand collars that divers often find. They produce a glue to cement the sand grains together into a protective ring for their eggs.

Moon Snails are predators of other shellfish, which they smother with their enormous foot. They are themselves sometimes eaten as Scungilli.

There are many types of worms, but most species are either too small or too secretive to be found by casual scuba divers. Nudibranchs are shell-less snails that resemble worms, while Teredos are nearly shell-less bivalves that also resemble worms.
