Ammotheidae
Ammotheidae is the most diversified group of the class Sea spider, Pycnogonida, with 297 species described in more than 20 genera, of which only ''Nymphopsis'' and ''Sericosura'' were found to be monophyletic. Despite its internal taxonomic uncertainty, studies on 18S rRNA supports its monophyly, and the subdivision on Achelinae and Ammotheinae subfamilies. Genera The family Ammotheidae comprises the following subfamilies: * ''Achelia'' Hodge, 1864 * ''Acheliana'' Arnaud, 1971 * ''Ammothea'' Leach, 1814 * ''Ammothella'' Verrill, 1900 * ''Austroraptus'' Hodgson, 1907 * ''Biammothea'' Pushkin, 1993 * ''Cilunculus'' Loman, 1908 * ''Dromedopycnon'' Child, 1982 * ''Elassorhis'' Child, 1982 * ''Hedgpethius'' Child, 1974 * ''Hemichela'' Stock, 1954 * ''Megarhethus'' Child, 1982 * ''Nymphopsis'' Haswell, 1885 * ''Oorhynchus'' Hoek, 1881 * ''Paranymphon'' Caullery, 1896 * ''Proboehmia'' Stock, 1991 * ''Prototrygaeus'' Stock, 1975 * ''Scipiolus'' Loman, 1908 * ''Serico ...

Sea Spider
Sea spiders are marine arthropods of the order Pantopoda ( ‘all feet’), belonging to the class Pycnogonida, hence they are also called pycnogonids (; named after ''Pycnogonum'', the type genus; with the suffix '). They are cosmopolitan, found in oceans around the world. The over 1,300 known species have legs ranging from to over . Most are toward the smaller end of this range in relatively shallow depths; however, they can grow to be quite large in Antarctic and deep waters. Although "sea spiders" are not true spiders, or even arachnids, their traditional classification as chelicerates places them closer to true spiders than to other well-known arthropod groups, such as insects or crustaceans. This is in dispute, however, as genetic evidence suggests they may be the sister group to all other living arthropods. Description Sea spiders have long legs in contrast to a small body size. The number of walking legs is usually eight (four pairs), but the family Pycnogonidae hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
