The bluntnose guitarfish or fiddlefish (Acroteriobatus blochii) is a species of fish in the Rhinobatidae family. It is found in Namibia and South Africa. Its natural habitats are shallow seas and estuarine waters. It is threatened by habitat loss. They are often referred to as ‘shark-like rays’, and because of their habitats in shallow seas, it increases their exposure to fishing pressures. Acroteriobatus blochii are confirmed to be closely related to Acroteriobatus annulatus, which can impact conservation planning.
