A rare deep-sea creature dubbed the 'headless chicken monster' has been filmed for the first time by Australian researchers. The elusive Enypniastes eximia sea cucumber, which is usually only found in the Gulf of Mexico, was spotted in the Southern Ocean in the East Antarctic using camera technology developed by the Australian Antarctic Division (AAD). 'Some of the footage we are getting back from the cameras is breathtaking, including species we have never seen in this part of the world,' AAD Program leader Dr Dirk Welsford said.
