[1] This group is assumed to have originated in the late Triassic or in the early Jurassic.

Hermit crabs who cannot generate their own shells use the moon snails old shells. endobj The animal can shrink by discharging water, sliding into its shell, and sealing the opening by closing its operculum. Kabat A.R. Moon snail shells are attractive and relatively large, and often popular in jewellery and ornamentation. Like the shore crabs, kelp crabs are herbivores most of the time. secrete an acidic chemical that softens the shell, and the snails easily drill through and eat the soft-shelled clams. They will also attack almost any other shelled mollusk they encounter in the sand, such as scaphopods and other gastropods, including other moon snails.
