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.
Anthozoa is a class 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.
The aggregating anemone (Anthopleura elegantissima), or clonal anemone, is the most abundant species of sea anemone found on rocky, tide swept shores along the Pacific coast of North America. [1] This cnidarian hosts endosymbiotic algae called zooxanthellae that contribute substantially to primary productivity in the intertidal zone . [ 2 ]
Now that scientists have enticing stem cell candidates, future studies will delve deeper into the mechanisms that make cnidarians, such as the scarlet sea anemone, adept fighters against the ...
Cnidarians include corals, sea anemones, jellyfish and hydrozoans. They form a phylum containing over 10,000 [ 32 ] species of animals found exclusively in aquatic (mainly marine) environments. Their bodies consist of mesoglea , a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick .
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
The Enthemonae is a suborder of sea anemones in the order Actiniaria.It comprises those sea anemones with typical arrangement of mesenteries for actiniarians. [1]The Enthemonae is any member of the invertebrate suborder characterised by soft bodied, marine animals that look like flowers which primarily attach to hard or rigid surfaces, such as coral or rocks.
The starlet sea anemone (Nematostella vectensis) is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced populations along the coast of southeast England and the west coast of the United States (class Anthozoa, phylum Cnidaria, a sister group of Bilateria).
