Andvakiidae is a family of sea anemones.
The following genera are recognized: [2]
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.
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.
Edwardsia is a genus of sea anemones, the type of the family Edwardsiidae. They have eight mesenteries and live in tubes in the sand. The name, in Neo-Latin, commemorates the French zoologist Henri Milne-Edwards.
Corallimorpharia is an order of marine cnidarians closely related to stony or reef building corals (Scleractinia). They occur in both temperate and tropical climates, although they are mostly tropical. Temperate forms tend to be very robust, with wide and long columns, whereas tropical forms tend to have very short columns with a wide oral disc and very short tentacles. The tentacles are usually arranged in rows radiating from the mouth. Many species occur together in large groups, although there are recorded instances of individuals. In many respects, they resemble the stony corals, except for the absence of a stony skeleton. Morphological and molecular evidence suggests that they are very closely related to stony corals.
Amphianthus is a genus of sea anemones. It is the only genus in the monotypic family Amphianthidae.
Hormathiidae is a family of sea anemones in the class Anthozoa.
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.
Sagartia is a genus of sea anemones in the family Sagartiidae. The genus was first described by Philip Henry Gosse in 1855 and the image is his painting of several species found in British waters included in his book, A history of the British sea-anemones and corals.
Peachia is a genus of sea anemone in the family Haloclavidae. Members of this genus typically burrow into soft substrates. The only part of the animal that is normally visible is the oral disc and tentacles which lie flat on the sand in a star shape. The type species is Peachia cylindrica.
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.
Patrik Ulf Anders Carlgren is a Swedish professional footballer who plays as a goalkeeper.
Sagartiogeton is a genus of sea anemones in the family Sagartiidae.
Metridioidea is a superfamily of sea anemones in the order Actiniaria. Members of this clade live in shallow subtropical waters worldwide.
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.
Kadosactinidae is a family of sea anemones.
Anthosactis is a genus of cnidarians belonging to the family Actinostolidae.
Sideractinidae is a family of corals belonging to the order Corallimorpharia.
