Cryptolepas is a genus of whale barnacles in the family Coronulidae. There are two described species in Cryptolepas, one of which is extinct. [1] [2]
These species belong to the genus Cryptolepas:
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 larval stages. Around 1,000 barnacle species are currently known. The name "Cirripedia" is Latin, meaning "curl-footed". The study of barnacles is called cirripedology.
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.
Megabalanus is a genus of barnacles in the family Balanidae. Members of the genus grow to 7 cm (2.8 in) in length and inhabit the lower intertidal zone.
Chthamalus 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.
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.
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.
In the past, Catophragminae has been considered a subfamily of barnacles of the family Catophragmidae. The subfamily was elevated to family rank in 1976, and research published in 2021 by Chan et al. resulted in the genera of the subfamily being assigned directly to the family, without subfamily groupings, and this subfamily is no longer used.
Concavus is a genus of barnacles.
Cryptolepas rhachianecti is a species of whale barnacle that lives as a passenger on the skin of gray whales and certain other species of whale in the northern Pacific Ocean.
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.
Lithoglyptida is an order of barnacles in the class Thecostraca. There are 2 families and more than 40 described species in Lithoglyptida.
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.
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.
Waikalasma is a genus of symmetrical sessile barnacles in the family Waikalasmatidae, the sole genus of the family. There are at least three described species in Waikalasma.
