Description

The southern stargazer (Astroscopus y-graecum) is a remarkable bottom fish of the family Uranoscopidae from the western Atlantic. The species has a broad, armoured head with the eyes and the upward-pointing mouth on top, so that, buried in the sand, it can look up and lunge at passing prey. The brown body is studded with white spots and reaches about 43 cm. Notably the species has an electric organ behind the eyes with which it can deliver a shock, and bears venomous spines above the pectoral fins. When handled it can give both an electric shock and a painful sting.
