Description

The Blackfin stargazer is a stargazer (Uranoscopidae) from coastal water of the Indo-West Pacific. The species grows to about 30 cm and has a stocky body with a large, bony head, eyes on top of the head and an upturned mouth. As an ambush predator it lies buried on sand and mud bottoms with only its eyes showing and snaps at passing fish. Behind the head it carries venomous shoulder spines and it can deliver a mild electric shock with an electric organ; a sting is very painful.
