Description

The lesser sandshark is a guitarfish from southern African waters, ranging from Angola along South Africa to southern Mozambique. It has a flattened, shark-like body with a violin-shaped head disc and two dorsal fins on the tail. A bottom-dweller, the fish lives on sandy coastal bottoms down to about 75 metres and feeds on crustaceans, bivalves, polychaete worms and small fishes. The species is ovoviviparous: 2 to 10 pups are born in summer. Its flesh is esteemed and the fish is taken by surf anglers. Owing to fishing pressure the species is listed as Vulnerable (VU) on the IUCN Red List.
