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.
Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the genus Symbiodinium living inside nutritive cells.
These sea anemones exclusively reside within the shallow waters of the tropical Indo-Pacific area and are in the main family of sea anemones that hosts several varieties of clownfishes. [1] Most sea anemone species are harmless to humans, but at least some Stichodactyla are highly venomous and their sting may cause anaphylactic shock and organ ...
Invertebrate sea life includes the following groups, some of which are phyla: The 49th plate from Ernst Haeckel's Kunstformen der Natur, 1904, showing various sea anemones classified as Actiniae, in the Cnidaria phylum "A variety of marine worms": plate from Das Meer by M.J. Schleiden (1804–1881) Acoela, among the most primitive bilateral ...
Tube-dwelling anemones or cerianthids look very similar to sea anemones, but belong to an entirely different subclass of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live and can withdraw into tubes, which are made of a fibrous material, which is made from secreted mucus and threads of nematocyst-like organelles ...
Exaiptasia is a genus of sea anemone in the family Aiptasiidae, native to shallow waters in the temperate western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.It is monotypic with a single species, Exaiptasia diaphana, and commonly known as the brown anemone, glass anemone, pale anemone, or simply as Aiptasia.
In humans, stems cells allow limited regeneration of certain cells in our body (which is why they’re central to the exploration of anti-aging therapies), however, other animals display much ...
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.
