Juliidae
The family Juliidae includes the "bivalved snails"--unique among gastropod mollusks in having clam-like shells into which the body can be withdrawn. They were first described as bivalves from fossil material and only recognized as gastropods when living animals were discovered in 1959. Diurnally active, they feed on algae of the genus Caulerpa. Some are among the few gastropods to have green shells. At least seven species are known from Hawaii in at least two genera (Berthelinia and Julia).
