Oculina is a genus of colonial stony coral in the family Oculinidae. These corals are mostly found in the Caribbean Sea, the Gulf of Mexico and Bermuda but some species occur in the eastern Pacific Ocean. They occur at depths down to 1000 metres.
Davidaster is a genus of crinoids. According to the World Register of Marine Species, a number of species that originally were included in the genus Nemaster are now included in Davidaster. Members of this genus have wedge-shaped arms, except for the basal ones, often longer than they are wide. The mouth is off centre and there are no pinnule combs after pinnule 3. The primary comb has the teeth widely separated and confluent with the lateral edge of the segment.
Dendrophylliidae is a family of stony corals. Most members are azooxanthellate and thus have to capture food with their tentacles instead of relying on photosynthesis to produce their food. The World Register of Marine Species includes these genera in the family:
Balanophyllia is a genus of solitary corals in the order of stony corals.
Stylaster is a genus of hydroids in the family Stylasteridae.
Dendrophyllia is a genus of stony cup corals in the family Dendrophylliidae. Members of this genus are found at depths down to about 900 metres (3,000 ft). They are azooxanthellate corals, meaning that they do not contain symbiotic photosynthetic dinoflagellates as do many species of coral.
Schizocyathidae is a family of stony corals. There are currently three genera included in this family and each of them is monotypic. Members of the family are azooxanthellate, deep water species.
Coenosmilia is a genus of small corals in the family Caryophylliidae.
Dasmosmilia is a genus of small corals in the family Caryophylliidae.
Chiridota is a genus of sea cucumbers in the family Chiridotidae. It is an extant genus but some fossil species are known.
The pourtalesiids (Pourtalesiidae) are a family of irregular sea urchins that live in the deep sea. They are secondarily bilateral-symmetrical and like other representatives of the taxon Holasteroida they lack the lantern of Aristotle, which is typical for many other sea urchins. The genus Pourtalesia was named after Louis-François de Pourtalès who first collected these animals while dredging at a depth of 600 m. The family is known already from the Upper Cretaceous (Maastrichtian) and is distributed worldwide.
Gardinerpiscis is an extinct genus of prehistoric actinopterygian fish that lived during the Kungurian age of the early Permian epoch in what is now Kazakhstan. It was originally named "Gardineria" by Kazantseva-Selezneva (1981). Because this genus name was already given to an extant scleractinian coral, the new name Gardinerpiscis was erected for the Permian fish. The genus includes a single species (monotypy): Gardinerpiscis akkolkensis.
Deltocyathus is a genus of cnidarians belonging to the monotypic family Deltocyathidae.
Madracis is a genus of cnidarians belonging to the family Pocilloporidae. The genus has a cosmopolitan distribution.
Enallopsammia is a genus of cnidarians belonging to the family Dendrophylliidae.
Gardineriidae is a family of corals belonging to the order Scleractinia.
Eguchipsammia is a genus of corals belonging to the family Dendrophylliidae.
Trochocyathus is a genus of corals in the family Caryophylliidae. Living species are found in waters near Hawai'i at depths of 64 to 1,020 meters. Fossil species are found as far back as the latest Paleocene in the Dilwyn Formation of Australia, in the late Cretaceous in the Woodbury Formation of New Jersey, and in Suffolk.
Canda is a genus of bryozoans belonging to the family Candidae.
Anthemiphyllia is a genus of corals within the family Anthemiphylliidae. There are currently 8 extant and 2 extinct species assigned to the genus.
