The Antarctic predatory fish ( Harpagifer ) ( Gr .: harpago = robbery, Lat .: ferre = bring) are a family of the Antarctic fish (Notothenioidei). They live on the coast of Antarctica and the southern part of South America, as well as on sub-Antarctic islands such as the Kerguelen and Macquarie Island .
features
The fish are elongated, the bullheads similar ground dwellers and are 7 to 9.5 centimeters long. Your body is flaky. They have two clearly separated dorsal fins , the first is short and supported by one to seven flexible fin spines. The mouth can be turned forward (protractile). A goatee is missing. The gill cover and the gill cover are each covered with a strong sting. The gill membranes have grown together on the gill isthmus. The species of Antarctic predatory fish have 34 to 37 vertebrae and three hypuralia (bones of the tail skeleton).
Systematics
The Antarctic predatory fish form a monophyletic clade with the Artedidraconidae , which were previously assigned to them as a subfamily, and are their sister group .
