The starlet sea anemone is used as a model organism in research. [34] It is easy to care for in the laboratory and a protocol has been developed which can yield large numbers of embryos on a daily basis. [35] There is a remarkable degree of similarity in the gene sequence conservation and complexity between the sea anemone and vertebrates. [35]
a Beroe ovata, b unidentified cydippid, c "Tortugas red" cydippid, d Bathocyroe fosteri, e Mnemiopsis leidyi, and f Ocyropsis sp. [17]. Among animal phyla, the ctenophores are more complex than sponges, about as complex as cnidarians (jellyfish, sea anemones, etc.), and less complex than bilaterians (which include almost all other animals).
Actinostephanus haeckeli, also known as the sea snake anemone or Haeckel's sea anemone, [1] is a species of sea anemone in the family Actinodendridae. [2] Environment
Sea anemones (/ ə ˈ n ɛ m. ə. n i / ə-NEM-ə-nee) are a group of predatory marine invertebrates constituting the order Actiniaria. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia.
Located along the eastern coast of the U.S., with a few introduced populations scattered along the western U.S. coast and the southeast coast of Britain, this sea anemone is a member of the sea ...
Anthozoa is a subphylum of marine invertebrates which includes sessile cnidarians such as the sea anemones, stony corals, soft corals and sea pens.Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as planktons.
While the species is currently recognized as a sea anemone, [1] a phylogenetic study was completed in 2014, in which three genes of mitochondrial DNA and two genes from the nucleus of over a hundred different sea anemones were compared, suggesting that the species instead belongs in a new order.

The polyps of Umimayanthus parasiticus superficially resemble rather small sea anemones. They grow either singly or in small groups of two or three on the surface of certain species of sponge. The polyps are joined by a thin layer of tissue called coenenchyme and occur at densities of 3 to 10 per square centimetre (20 to 60 per square inch). [2]
