Description

The common guitarfish is a guitarfish of the family Rhinobatidae reaching about 185 cm long. It forms a transition between shark and ray: the front is flattened and heart-shaped with a pointed, translucent snout, while the rear body is sturdy and shark-like, with two dorsal fins and a powerful tail. The upper side is plain grey-brown with a pale belly. Unlike stingrays it lacks a venomous spine. The species lives on sand and mud bottoms of shallow coastal water, where it often lies half-buried. On the bottom it searches for crabs, shrimps, crustaceans, molluscs and small fish, which it crushes with flat tooth plates. Through heavy fishing and bycatch it has declined sharply and is assessed as Critically Endangered (CR).
