Description

The granulated guitarfish is a guitarfish (Glaucostegidae) from coastal waters of the northern Indian Ocean and Indo-West Pacific. The species grows to about 2.8 metres and has a flattened, guitar-shaped body with a pointed snout and a sturdy, shark-like tail section; the back is set with fine granules. Unlike stingrays it has no venomous spine. As a bottom-dweller it lives on sand and mud bottoms and crushes molluscs, crustaceans and small fish. The fish is harmless to humans.
