Description

The Yellowtail stargazer is a stargazer (Uranoscopidae) from sand and mud bottoms around Australia and the Indo-West Pacific. The species grows to about 25 cm and has a stocky body with a large, upturned mouth and high-set eyes, so it can lurk almost fully buried on the bottom. As an ambush predator it lunges up at passing small fish. Behind the head it bears venomous shoulder spines that can give a very painful puncture wound.
