Description

The African wedgefish is a large wedgefish of the family Rhinidae reaching about 3 metres long. It forms a transition between ray and shark: the front is flattened and wedge-shaped, with a pointed snout, while the rear body is powerful and shark-like, with two tall dorsal fins and a strong tail. Rows of thorns run over the head and back. Unlike stingrays it lacks a venomous spine. The species lives on sand and mud bottoms of shallow coastal water and estuaries along the West African coast. On the bottom it crushes crabs, crustaceans, shellfish and small fish with flat tooth plates. Through heavy fishing - partly for the very valuable fins - it has declined sharply and is assessed as Critically Endangered (CR).
