Platylepas is a genus of barnacles in the family Platylepadidae of the subphylum Crustacea. [1] [2]
Species within the genus Platylepas recognised by the World Register of Marine Species include: [1]
Barnacles are a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and are hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. Around 1,000 barnacle species are currently known.
Thecostraca is a class of marine invertebrates containing over 2,200 described species. Many species have planktonic larvae which become sessile or parasitic as adults.
Whale barnacles are species of acorn barnacle that belong to the family Coronulidae. They typically attach to baleen whales, and sometimes settle on toothed whales. The whale barnacles diverged from the turtle barnacles about three million years ago.
Pollicipes is a genus of goose barnacles, first described by William Elford Leach in 1817. It comprises four species of marine suspension-feeders.
Semibalanus is a genus of barnacles, comprising four species. It is the only genus in the subfamily Semibalaninae.
The Catophragmidae are a family of barnacles in the superfamily Chthamaloidea with eight shell wall plates, surrounded by several whorls of imbricating plates. The basis is membranous.
Paralepas is a genus of goose barnacles in the family Heteralepadidae.
Clistosaccidae is a family of parasitic barnacles belonging to the bizarre and highly apomorphic infraclass Rhizocephala, which is part of the barnacle subclass Cirripedia.
Dosima is a genus of goose barnacles in the family Lepadidae. There are at least two described species in Dosima.
Austrobalanus is a genus of symmetrical sessile barnacles in the family Austrobalanidae, the sole genus of the family. There are at least three described species in Austrobalanus.
Eolepadomorpha is an extinct order of barnacles in the class Thecostraca. There are 2 families and about 14 described species in Eolepadomorpha.
Pollicipedomorpha is an order of pedunculated barnacles in the class Thecostraca. There are 3 families and more than 30 described species in Pollicipedomorpha.
Octomeris is a genus of star barnacles in the family Chthamalidae. There are at least three described species in Octomeris.
Verruca is a genus of asymmetrical sessile barnacles in the family Verrucidae. There are about 20 described species in Verruca, around half of them extinct.
Perforatus is a genus of acorn barnacles in the family Balanidae. There is one described species in Perforatus, P. perforatus.
Notomegabalanus is a genus of acorn barnacles in the family Balanidae. There are about 12 described species in Notomegabalanus.
Notobalanus is a genus of acorn barnacles in the family Balanidae. There are at least two described species in Notobalanus.
Chirona is a genus of acorn barnacles in the family Balanidae. There are about six described species in Chirona.
Pirusaccus is a genus of parasitic barnacles in the family Pirusaccidae, the sole genus of the family. There is one described species in Pirusaccus, P. socialis.
Triangulus is a genus of parasitic barnacles in the family Triangulidae, the sole genus of the family. There are at least four described species in Triangulus.
