Description

Bloch's guitarfish is a guitarfish from the western Indian Ocean, off the coast of southern Africa. The species grows to about 100 cm and has a form between shark and ray: a flattened, angular front with a blunt snout and a powerful, shark-like rear body with a well-developed tail. Unlike stingrays it lacks a venomous spine. As a bottom-dweller it often lies half-buried in sand and mud bottoms of shallow coastal water and searches for molluscs, crustaceans and small fish. The fish is harmless to humans. The IUCN assesses the species as Least Concern (LC).
