Catophragmidae
The Catophragmidae are a family of barnacles in the superfamily Chthamaloidea with eight shell wall plates (rostrum, carina, paired rostrolatera, carinolatera I and carinolatera II), surrounded by several whorls of imbricating plates. The basis is membranous. This family occupies lower to upper midlittoral warm seas of the Pacific Coast of Central America, Caribbean, Bermuda, and Australia/Tasmania. These populations are highly disjunct and can be seen as relictual. The family contains these genera: All genera are at present monotypic. *''Catolasmus'' Ross & Newman, 2001 *''Catomerus'' Pilsbry, 1916 *''Catophragmus ''Catophragmus'' is the originally named genus of the family Catophragmidae.

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] |
