The Stichasteridae are a small family of Asteroidea (sea stars) in the order Forcipulatida. Genera were formerly unassigned, or in the family Asteriidae.
The World Register of Marine Species lists these genera within the family Stichasteridae: [1]
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 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.
The Valvatida are an order of starfish in the class Asteroidea, which contains 695 species in 172 genera in 17 families.
The Asterinidae are a large family of sea stars in the order Valvatida.
The Astropectinidae are a family of sea stars in the order Paxillosida. Usually, these starfish live on the seabed and immerse themselves in soft sediment such as sand and mud.
Astropecten is a genus of sea stars of the family Astropectinidae.
The Asteriidae are a diverse family of Asteroidea in the order Forcipulatida. It is one of three families in the order Forcipulatida.
Goniasteridae constitute the largest family of sea stars, included in the order Valvatida. They are mostly deep-dwelling species, but the family also include several colorful shallow tropical species.
Ceramaster is a genus of cushion stars in the family Goniasteridae. The species in this genus have no arms. They live in deeper waters than most sea stars.
The Forcipulatida are an order of sea stars, containing three families and 49 genera.
Astyris is a genus of sea snails, marine gastropod molluscs in the family Columbellidae, the dove snails.
Henricia is a large genus of slender-armed sea stars belonging to the family Echinasteridae. It contains about fifty species.
Hormathiidae is a family of sea anemones in the class Anthozoa.
Scleraxonia is a suborder of corals, a member of the phylum Cnidaria.
Asteropseidae is a family of sea stars. Members of the family have relatively broad discs and five short tapering arms.
The Solasteridae are a family of sea stars.
Plexauridae is a family of marine colonial octocorals in the phylum Cnidaria. Members of this family are found in shallow tropical and subtropical seas. Many species contain symbiotic photosynthetic protists called zooxanthellae.
Poraniidae is a family of starfishes in the order Valvatida.
Neomorphaster is a genus of echinoderms belonging to the family Stichasteridae.
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.
Stichaster striatus, the common light striated star, is a species of starfish in the family Stichasteridae, found in the southeastern Pacific Ocean. It was first described by the German zoologists Johannes Peter Müller and Franz Hermann Troschel in 1840.
