Edwardsiella is a genus of sea anemones in the family Edwardsiidae. It is named in honour of Henri Milne-Edwards, an eminent French zoologist.
The following species are listed by the World Register of Marine Species. [1]
Actiniidae is the largest family of sea anemones, to which most common, temperate, shore species belong. Most members of this family do not participate in symbioses with fishes. Three exceptions are the bubble-tip anemone, snakelocks anemone and Urticina piscivora.
Octineon is the sole genus of sea anemones in the monotypic family Octineonidae.
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different class of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Within the tubes of these ceriantharians, more than one polyp is present, which is an exceptional trait because species that create tube systems usually contain only one polyp per tube. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own class, Ceriantharia.
Halcampidae is a family of sea anemones. Members of this family usually live with their column buried in sand or other soft substrates.
Isozoanthus is a genus of anemone-like anthozoans in the order Zoantharia.
Cerianthus is a genus of tube-dwelling anemones in the family Cerianthidae. Members of the genus are found worldwide. They are predators, scavengers and omnivores.
Edwardsiidae is a family of sea anemones. Edwardsiids have long thin bodies and live buried in sediments or in holes or crevices in rock.
Zoanthus is a genus of anthozoans in the family Zoanthidae. It is the type genus for its family and order.
Haliclystidae is a family of stalked jellyfish in the order Stauromedusae.
Palythoa is a genus of anthozoans in the order Zoantharia.
Sagartiogeton is a genus of sea anemones in the family Sagartiidae.
Cerianthidae is a family of tube-dwelling anemones in the order Spirularia of the subclass Ceriantharia.
Arachnactidae is a family of tube-dwelling anemones in the order Ceriantharia. It is the only family in the monotypic order Penicillaria and comprises around 38 species. They differ from other ceriantharians in the makeup of their cnidome, the relative sizes of the oral discs and the shape and structure of the mesenteries. These tube anemones dwell in parchment-like tubes immersed in soft sediment, and have two whorls of tentacles, the outer ones being much longer than the inner ones.
Actinostolidae is a family of sea anemones in the order Actiniaria. Members of this family are deep sea species, with some occurring at hydrothermal vents.
Actinostola is a genus of sea anemones in the order Actiniaria. All members of this genus are deep-sea species, with some occurring at hydrothermal vents.
Diadumene is a genus of sea anemones. It is the only genus in the monotypic family Diadumenidae.
Paranthus is a genus of sea anemones in the family Actinostolidae.
Pachycerianthus is a genus of marine tube-dwelling anemones in the family Cerianthidae.
Andvakiidae is a family of sea anemones.
Boloceroididae is a family of sea anemones. It has a cosmopolitan distribution in tropical and temperate oceans.
