Moon Snail Shell


These Moon Snails are carnivorous! Adult moon snails are strict predators and mostly eat bivalves.  As many of their prey live at depths of up to 20cm or more, the snails have to burrow quite deeply to find them.  Burrowing by moon snails is enabled by a large foot that is capable of inflating up to 4 times the shell volume through uptake of seawater.  The inflation is quick, allowing fast penetration and displacement of sand. The moon snail catches hold of its prey and hauls it to the surface to begin drilling.

Shell measures approx 4"-5".
