(PhysOrg.com) -- An isopod that replaces a fish's tongue has been discovered for the first time in the Channel Islands in Europe. The marine isopod, described by its finder as hideous and vicious, is a rare find.
True crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (Greek: βραχύς / brachys = short, οὐρά / οura = tail), or where the reduced abdomen is entirely hidden under the thorax. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs and crab lice – are not true crabs.
