Description

The Atlantic stargazer is a stout bottom fish of the family Uranoscopidae reaching about 56 cm. The species owes its name to the build of its head: the eyes and the nearly vertical, upturned mouth sit on top of the flattened head. The stargazer buries itself in sand and mud bottoms of the eastern Atlantic, the Mediterranean and the Black Sea, with only the eyes showing. From this ambush it lures small fish and crustaceans with a worm-like flap in the mouth and sucks them in at lightning speed. It has venomous shoulder spines and weak electric organs behind the eyes. Despite the spines it is eaten in southern Europe; care is needed when handling it.
