Description

The giant guitarfish, also called the whitespotted wedgefish, is a large ray-like fish of the family Rhinidae from the western Indian Ocean. The species can reach over three metres and has a wedge-shaped, flattened front with the disc and a muscular, shark-like tail with two dorsal fins. The grey upper side bears rows of white spots. It lives inshore and in shallow estuaries and feeds on crabs, lobsters, bivalves, squid and small fishes. The species is ovoviviparous. Owing to strong demand for meat and especially fins in Asian markets it is severely overfished and assessed by the IUCN as critically endangered (CR).
