Elminiidae is a family of symmetrical sessile barnacles in the order Balanomorpha. There are about 5 genera and 12 described species in Elminiidae. [2] [3]
These genera belong to the family Elminiidae:
Thoracica is an infraclass of crustaceans which contains the most familiar species of barnacles found on rocky coasts, such as Semibalanus balanoides and Chthamalus stellatus. They have six well-developed limbs, and may be either stalked or sessile. The carapace is heavily calcified. The group includes free-living and commensal species.
The Balanidae comprise a family of barnacles of the order Balanomorpha. As a result of research published in 2021 by Chan et al., the members of the family Archaeobalanidae were merged with this family.
The Balanomorpha are an order of barnacles, containing familiar acorn barnacles of the seashore. The order contains these families:
Lepadidae is a family of goose barnacles, erected by Charles Darwin in 1852. There are about five genera and more than 20 described species in Lepadidae.
Calanticidae is a family of acorn barnacles in the order Calanticomorpha. There are about 12 genera and more than 60 described species in Calanticidae.
The Chthamaloidea are a subdivision of Balanomorpha proposed by Newman and Ross to include barnacles with shell wall composed of rostrum, carina, and one to three pairs of latera, rarely supplemented with one or more whorls of basal imbricating plates. The rostrolatus enters the sheath, but rarely fuses with the rostrum, as in the three higher superfamilies. Shell plates are simple in construction, solid, and incorporate organic chitin between carbonate layers. Opercular plates are deeply interlocked, and in some genera, may become concrescent with age. Soft part morphology includes concave labrum without notch in the central part. Cirrus III more resembles Cirrus IV than II, or may be intermediate in structure. Caudal appendages present in some species.
Austrominius is a genus of barnacles belonging to the family Elminiidae.
Scalpellomorpha is an order of acorn barnacles in the class Thecostraca. There are about 11 families in 3 superfamilies and more than 450 described species in Scalpellomorpha.
Iblidae is a family of crustaceans belonging to the order Iblomorpha. There are two genera in the family, each with its own subfamily.
Pachylasmatidae is a family of symmetrical sessile barnacles in the order Balanomorpha. There are about 10 genera and at least 30 described species in Pachylasmatidae.
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.
Iblomorpha is a small order of barnacles in the class Thecostraca. There are only two families and about eight described species in Iblomorpha. In this group we find barnacles that use calcium phosphate in their shell, and species that protect themselves against predators with poison.
Eolepadomorpha is an extinct order of barnacles in the class Thecostraca. There are 2 families and about 14 described species in Eolepadomorpha.
Calanticomorpha is an order of acorn barnacles in the class Thecostraca. There are 3 families and more than 90 described species in Calanticomorpha.
Pollicipedomorpha is an order of pedunculated barnacles in the class Thecostraca. There are 3 families and more than 30 described species in Pollicipedomorpha.
Epopella is a genus of symmetrical sessile barnacles in the family Tetraclitidae. There are about six described species in Epopella.
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.
Notomegabalanus is a genus of acorn barnacles in the family Balanidae. There are about 12 described species in Notomegabalanus.
Idioiblidae is a family of normal barnacles in the order Iblomorpha. There are at least three genera and about five described species in Idioiblidae.
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.
