Starfish genera

Asterias is a genus of the Asteriidae family of sea stars. It includes several of the best-known species of sea stars, including the (Atlantic) common starfish, Asterias rubens, and the northern Pacific seastar, Asterias amurensis. The genus contains a total of eight species in all. All species have five arms and are native to shallow oceanic areas (the littoral zone) of cold to temperate parts of the Holarctic. These starfish have planktonic larvae. Asterias amurensis is an invasive species in Australia and can in some years become a pest in the Japanese mariculture industry.

Astropecten is a genus of sea stars of the family Astropectinidae.

Coscinasterias is a genus of sea stars of the family Asteriidae.

Luidia is a genus of starfish in the family Luidiidae in which it is the only genus. Species of the family have a cosmopolitan distribution.

Fromia is a genus of starfish belonging to the family Goniasteridae.

Solaster is a genus of sea stars in the family Solasteridae.

Crossaster is a genus of sea stars in the family Solasteridae.

Patiriella is a genus of sea stars of the family Asterinidae. Many species formerly included in this genus have been transferred to other genera (Cryptasterina, Meridiastra, and Parvulastra). They are commonly known as carpet sea stars.

Patiria is a genus of starfish in the family Asterinidae from the Pacific Ocean, which are commonly known as bat stars.

Anthenea is a genus of sea stars in the family Oreasteridae. Members of this genus are most commonly observed off the coasts of Australia and southeast Asia.

Aquilonastra is a genus of small sea stars within the family Asterinidae. It has over 20 described species.

Marthasterias is a genus of starfish in the family Asteriidae. Both species in the genus are commonly known as the spiny starfish.

Anasterias is a genus of starfish in the family Asteriidae.

Lophaster is a genus of starfish within the family Solasteridae.

Podosphaeraster is a genus of echinoderms belonging to the monotypic family Podosphaerasteridae.

Heliaster is a genus of Asteroidea (sea stars) in the family Heliasteridae.

Labidiaster is a genus of echinoderms belonging to the family Heliasteridae. The species of this genus are found in the coasts of Antarctica and southernmost South America. The life cycle of all Labidiaster animals starts with an embryo that will hatch into planktonic larvae, and later transform into pentamerous juvenile sea stars.

Leptasterias is a genus of starfish in the family Asteriidae. Members of this genus are characterised by having six arms although five-armed specimens sometimes occur. L. muelleri is the type species. The taxonomy of the genus is confusing and Leptasterias hexactis seems to be a species complex. Some species brood their eggs.

Stellasteropsis is a genus of echinoderms belonging to the family Goniasteridae.

Sclerasterias is a genus of starfish in the family Asteriidae.

thumb|Detail view Choriaster is a monotypic genus in the family Oreasteridae, containing the single species Choriaster granulatus, commonly known as the granulated sea star. Other common names include big-plated sea star, hunter-five sea star and doughboy starfish.

Circeaster is a genus of abyssal sea stars in the family Goniasteridae.

Gymnanthenea is a genus of sea stars in the family Oreasteridae.

Archasteridae is a family of starfish found in shallow waters in the tropical Indo-Pacific region. The genus Astropus, previously included in this family, is now included in the genus Archaster with the single species, Astropus longipes (Gray, 1840), being accepted as Archaster lorioli Sukarno & Jangoux, 1977.

Cryptasterina is a genus of starfish belonging to the family Asterinidae. They occur in the Indian and Western Pacific Oceans in the littoral and shallow sublittoral zone.

Echinaster is a well-studied and common genus of starfish containing ~30 species and is the second-largest genus found within the family Echinasteridae. The genera Henricia and Echinaster encompass 90% of all the species found within the family Echinasteridae. It contains 30 species, however the number of species in this genus is still debatable because of uncertainty within the genera. This genus is currently sub-divided into two sub-genera: Echinaster and Othilia, evolutionary relationships between the sub-genera is not understood. Echinaster are found in the Pacific, Atlantic and Indian oce

Ophidiaster is a genus of echinoderms belonging to the family Ophidiasteridae.

Goniodiscaster is a genus of sea stars in the family Oreasteridae. Members of this genus can be found off the coasts of India, southeast Asia, and Australia. Other taxa commonly misidentified as this genus include Anthenea, Tosia, and Pentaceraster.

Nymphaster is a genus of echinoderms belonging to the family Goniasteridae.

Glyphodiscus is a genus of echinoderms belonging to the family Goniasteridae.

Marginaster is a genus of starfish in the family Poraniidae within the order Valvatida. It was named in 1881 by Edmond Perrier, and the type species is M. pectinatus. In 1995, a fossil brittle star was given the same generic name; however, because the name was preoccupied by the starfish, the brittle star required renaming. The brittle star was renamed Marginix in 2015.

Anthenoides is a genus of echinoderms belonging to the family Goniasteridae.

Mediaster is a genus of starfish in the family Goniasteridae. It was circumscribed in 1857 by William Stimpson for M. aequalis, the genus's type species. Its junior synonym is the genus Isaster, which was circumscribed in 1894 by Addison Emery Verrill for the species now known as M. bairdi. Verrill himself synonymized the two genus names in 1899.
