Ibla (crustacean)
''Ibla'' is a genus of barnacle. In 1848, Charles Darwin studied the genus and found species with hermaphrodites and tiny males. In this genus the number androdioecious species is uncertain because some authors use the words female and hermaphrodite interchangeably. Species Species in this genus include: *'' Ibla cumingi'' *''Ibla quadrivalvis ''Ibla quadrivalvis'' is a species of barnacle in the Iblidae family.

Barnacle
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale ( whale barnacles), a sea snake ('' Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" ( Sessilia), are sessile where they grow their shells directly onto the substrate. Peduncul ...
