Calliaster is a genus of starfish in the family Goniasteridae [1]
Species in the genus include:
The Ophidiasteridae are a family of sea stars with about 30 genera. Occurring both in the Indo-Pacific and Atlantic Oceans, ophidiasterids are greatest in diversity in the Indo-Pacific. Many of the genera in this family exhibit brilliant colors and patterns, which sometimes can be attributed to aposematism and crypsis to protect themselves from predators. Some ophidiasterids possess remarkable powers of regeneration, enabling them to either reproduce asexually or to survive serious damage made by predators or forces of nature. Some species belonging to Linckia, Ophidiaster and Phataria shed single arms that regenerate the disc and the remaining rays to form a complete individual. Some of these also reproduce asexually by parthenogenesis.
Astropecten is a genus of sea stars of the family Astropectinidae.
Coscinasterias is a genus of sea stars of the family Asteriidae.
Nardoa is a genus of sea stars in the family Ophidiasteridae.
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.
Coelopleurus is an extant genus of echinoids with fossil records dating back to the Eocene, with remains found in Europe and North America.
Spatangus is a genus of heart urchins in the Spatangidae family. The genus is synonymous with the previously recognised genera Prospatangus Lambert, 1902 and Spatagus. There are nine recognised species. The type species is Spatangus purpureus Müller, 1776 by subsequent designation.
The Oreasteridae are a family of sea stars in the class Asteroidea.
Anthenea is a genus of sea stars in the family Oreasteridae.
Pentaceraster is a genus of sea stars in the family Oreasteridae.
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.
Clypeaster, common name "cake urchins" or "sea biscuits", is a genus of echinoderms belonging to the family Clypeasteridae.
Coronaster is a genus of the Asteriidae family of starfish.
Ophiactis is a genus of brittle stars (Ophiuroidea).
Calliaster elegans is a species of starfish in the genus Calliaster.
