Families (and genera)
Arachnactidae Botrucnidiferidae Cerianthidae 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, known as ptychocysts. Cerianthids have a crown of tentacles that consists of two whorls of distinctly different sized tentacles. The outer whorl consists of large tentacles that extend outwards. These tentacles taper to points and are mostly used in food capture and defence. The smaller innner tentacles are held more erect than the larger lateral tentacles and are used for food manipulation and ingestion.[1] Taxonomy Suborder Spirularia contains the following genera[2]: Family Botrucnidiferidae Carlgren, 1912 Angianthula Leloup, 1964 Atractanthula Leloup, 1964 Botracnidifer Botruanthus Botrucnidiata Leloup, 1932 Botrucnidifer Calpanthula Cerianthula Beneden, 1898 Gymnanthula Leloup, 1964 Hensenanthula Ovanthula Sphaeranthula Family Cerianthidae Milne-Edwards et Haime, 1852 Anthoactis Leloup, 1932 Apiactis Beneden, 1898 Bursanthus Ceriantheomorphe Ceriantheopsis Carlgren, 1912 Cerianthus Delle Chiaje, 1830 Engodactylactis Isodactylactis Nautanthus Pachycerianthus Roule, 1904 Paradactylactis Parovactis Peponactis Plesiodactylactis Sacculactis Solasteractis Synarachnactis Carlgren, 1924 Syndactylactis Trichactis Suborder Penicilaria contains the following genera[3]: Family Arachnactidae McMurrich, 1910 Anactinia Annandale, 1909 Arachnactis Sars, 1846 Arachnanthus Carlgren, 1912 Dactylactis van Beneden, 1897 Isapiactis Carlgren, 1924 Isarachnactis Carlgren, 1924 Isarachnanthus Carlgren, 1924 Isovactis Ovactis Paranactinia Gallery Tube-dwelling-anemone at Monterey Bay Aquarium References ^ Brusca, R.C. & Brusca, G.J. 2002.
