Species: [1]
Anurognathus is a genus of small pterosaur that lived during the Late Jurassic period. Anurognathus was first named and described by Ludwig Döderlein in 1923. The type species is Anurognathus ammoni. The genus name Anurognathus is derived from the Greek αν/ an- ("without"), оυρα/ oura ("tail"), and γναθος/ gnathos ("jaw") in reference to its unusually small tail relative to other "rhamphorhynchoid" pterosaurs. The specific name ammoni honours the Bavarian geologist Ludwig von Ammon, from whose collection Döderlein had acquired the fossil in 1922.
Helicolenus is a genus of rockfishes found in the Indian, Atlantic and Pacific oceans.
Astropecten is a genus of sea stars of the family Astropectinidae.
Chondrocladia is a genus of carnivorous demosponges of the family Cladorhizidae. Neocladia was long considered a junior synonym, but has recently become accepted as a distinct genus.
Gorgonocephalus is a genus of marine basket stars in the class Ophiuroidea. Members of this genus are found in coldwater environments including the Arctic, the Antarctic, and deep-sea habitats. The scientific name comes from the Greek, gorgós meaning "dreaded" and -cephalus meaning "head", and refers to the similarity between these echinoids and the Gorgon's head from Greek myth with its coiled serpents for hair. The Greek mythological hero Perseus beheaded the Gorgon Medusa; when Perseus later dropped Medusa's head on the beach, her petrifying glance turned the nearby seaweed to stone, creating the first coral.

The Oreasteridae are a family of sea stars in the class Asteroidea.
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.
Metacrinus is a genus of stalked crinoids in the family Isselicrinidae. Members of this genus live on hard surfaces in deeper parts of the ocean. The genus has extant species and is also represented in the fossil record. Members of the genus grow to a maximum height of 60 centimetres (24 in) and are found in the eastern Pacific Ocean from Japan to Australia.
