picture info	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 ...

	Concavus ''Concavus'' is a genus of barnacles. Species , WoRMS recognizes the following two species: * ''Concavus concavus'' (Bronn, 1831) — Pliocene–early Pleistocene; Western Europe. * ''Concavus crassostricola'' Zullo, 1984 — Early Miocene; North Carolina and northern Florida. Taxonomic history The genus was circumscribed by William A. Newman in 1982. His original list of subgenera and species for the genus was the following: * ''Concavus'' genus ''Concavus'' subgenus * '' C. concavus'' ''Menesiniella'' subgenus * ''C. (M.) aquila'' * ''C. (M.) regalis'' ''Arossia'' subgenus * ''C. (A.) panamensis'' ''C. (A.) p. panamensis'' ''C. (A.) p. eyerdami'' * ''C. (A.) henryae'' Newman noted there were multiple fossil taxa in this genus, but didn't classify any except for the type species ''C. concavus''. In 1992, Victor A. Zullo revised the genus. He created a new subfamily, Concavinae, with '' Tamiosoma'' (the senior synonym of ''Menesiniella ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Chthamalus ''Chthamalus'' (χθαμαλός, "flat" or "on the ground") is a genus of barnacles that is found along almost all non-boreal coasts of the northern hemisphere, as well as many regions in the southern hemisphere. These small barnacles have been studied in part because of the taxonomic confusion over a group of species that, by and large, are morphologically and ecologically quite similar. In recent years, molecular techniques have identified a number of cryptic species that have been subsequently confirmed by taxonomists using morphological measurements. Most recently the genus has been shown to be paraphyletic, with the genus ''Microeuraphia'' nested within ''Chthamalus''. Field Identification Identification of barnacles in the field can be challenging, and identification of particular species of ''Chthamalus'' is not considered reliable in the field other than a few species. However, a notable distinction in the arrangement of wall plates can help biologists distinguish Chth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Chirona ''Chirona'' is a genus of acorn barnacles in the family Balanidae. There are about six described species in ''Chirona''.

	Chelonibia ''Chelonibia'' is a genus of acorn barnacles in the family Chelonibiidae of the subphylum Crustacea. Its members are epizootic and live attached to manatees, turtles, marine molluscs, crabs and horseshoe crabs in all tropical and subtropical oceans. In a few instances, they have been found on sea snakes, alligators and inanimate substrates, but they are not found in the typical habitats of barnacles – on rocks, docks or boats. Phylogeny They appear to be the sister group to the Balanidae. Fossils The fossil record of Chelonibia ranges back to the Miocene. Species The genus contains four extant species: '' Chelonibia caretta'' (Spengler, 1790) '' Chelonibia manati'' Gruvel, 1903 '' Chelonibia patula'' (Ranzani, 1818) ''Chelonibia testudinaria'' (Linnaeus, 1758 Events January–March * January 1 – Swedish biologist Carl Linnaeus (Carl von Linné) publishes in Stockholm the first volume (''Animalia'') of the 10th edition of Systema Naturae, 10th ...

	Chamaesipho ''Chamaesipho'' is a genus of four-plated notochthamaline barnacles in the Pacific Ocean limited to Australian/New Zealand temperate waters. They are intertidal in preference, and tend to form crowded columnar colonies. They can be identified in the field by having a four-plated wall, an unfused rostrum, and narrow opercular plates. ''Elminius'', which also inhabits the same area, has four plates in its shell wall. However, in ''Elminius'', the rostrum and rostrolatera are fused completely, and the compound rostrum receives the alae of the adjacent carinolaterals. In ''Chamaesipho'', the unfused rostrum bears alae, and closely resembles the carina in appearance. Definition and Discussion The primary shell wall is four plated, reduced from six by fusion of rostrolatera and carinolatera during ontogeny. No sutural interfolding is observed. With age, all plate sutures become concrescent. The basis is membraneous. Opercular plates are deeply articulated, but do not fuse together. Th ...

	Catophragmus ''Catophragmus'' is the originally named genus of the family Catophragmidae. At present, it is monotypical. It is a shallow water acorn barnacle of the Tropical Western Atlantic and Caribbean characterized by small accessory imbricating plates surrounding the base of the shell wall. Diagnosis and discussion The shell wall of ''Catophragmus'' has eight free plates, with no fusion, and all entering the wikt:sheath, sheath. In contrast to ''Catolasmus'', the other Northern Hemisphere catophragmid genus, imbricating plates extend only partway up the primary shell wall, and have usually four whorls, as opposed to 10. Many specimens have been recovered with few or no accessory plates remaining.491 As the imbricating whorls are small and apparently deciduous, this is explained as a result of grazing gastropods. The basis is calcareous, thin, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
