Aega Psora
''Aega psora'' is a species of isopod crustacean that parasitises a number of fish species in the North Atlantic. It is a serious ectoparasite of larger species of fish, particularly when they are injured. Description ''Aega psora'' is the type species of the genus ''Aega'' and was first described by Carl Linnaeus in 1758. It reaches in length and is mostly grey, with a faint dorsal stripe. It has slender mandibles and maxillae adapted for sucking blood and some of the setae (bristles) are hooked. The front three pairs of pereiopods (legs) cling on to its host, it inserts its mouthparts and blood is pumped rapidly into the gut. Other adaptations for this method of feeding include strong muscles in its oesophagus and large salivary glands. Distribution ''Aega psora'' is widespread throughout the North Atlantic Ocean and has been found in the Baltic Sea, the North Sea and the Irish Sea. In the northwestern Atlantic it is found between the Bay of Fundy and Cape Cod. Hosts ''Aega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
