Chthamalidae
The Chthamalidae are a family of chthamaloid barnacles, living entirely in intertidal/subtidal habitats, characterized by a primary shell wall of eight, six, or four plates, lacking imbricating plate whorls, and either membraneous or more rarely calcareous basis. They are not found below immediate subtidal habitats, and more likely are found in the highest tier of shallow-water barnacle fauna. They can be found in the most rigorous wave-washed locations, and some species are found in the surf zone above high tide mark, only receiving water from wave action at high tide. Definition and Discussion The shell wall consists of eight wall plates, which reduce to six, and four in some species. Plate reduction is accomplished by fusion of rostrolatera with adjacent laterals, or initially by suppression of carinolatus II, reducing plate number from eight to six. Unlike the superfamilies Coronuloidea and Balanoidea, the rostrum rarely fuses with rostrolatus. In soft parts, caud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sessilia
Sessilia is an unranked clade of barnacles, comprising the barnacles without stalks, or acorn barnacles. They form a monophyletic group and are probably derived from stalked or goose barnacles. Sessilia is divided into two orders. The Verrucomorpha contain two families, Verrucidae and Neoverrucidae Neoverrucidae is a family of crustaceans belonging to the order Scalpellomorpha Scalpellomorpha is an order of acorn barnacles in the class Thecostraca Thecostraca is a Class (biology), class of marine invertebrates containing over 2,200 des ..., and the remaining 14 families are in the order Balanomorpha.
