They catch and eat small organisms in the water so they grow and slough their shell six times before transforming into cypris larvae. Many larvae are eaten by other creatures that eat suspended particles. Classification:Cirripedia nauplius larvae are crustaceans under the arthropod group.

During successive moults, trunk segments and additional appendages are usually added. CYPRIS LARVA In subclasses Ostracoda and Cirripedia the nauplius larva changes into Cypris larva. Body of cypris is enclosed into a bivalve shell which is secured by an adductor muscle There is one pair of compound eyes. The antennule is large and especially modified for attachment to substratum with cement gland.
