Bowmouth Guitarfish (Rhina ancylostoma)


The Bowmouth Guitarfish or Rhina ancylostoma is a saltwater fish found in the tropical waters of the Pacific and Indian Oceans.  Upon first glance you would think this fish was a mutant, part Ray and part Shark, but it is in fact a Ray and the sole member of the family Rhinidae.  As you can see in the pictures, it has shark-like dorsal and tail fins with a broad head containing thorny ridges that run down its back.  These thorns are used for self defense when attacked by predators such as the Tiger Shark.  Its mouth is on its underside where it uses it to feed off of the bottom.   

The Bowmouth Guitarfish is also known as the Mud Skate or Shark Ray and is found around sandy bottoms or just on the outskirts of reefs.  They feed on crustaceans, molluscs, and small fishes.   This species of Guitarfish is quite large growing to 2.7 m (8.9 ft) in length and weighing 135 kg (300 lb)!  Over the years it has been proven that they are quite adaptable to captivity and are displayed in many aquariums throughout the world.  You can check out the Bowmouth Guitarfish underwater in the videos below.

The second video is NOT a bowmouth guitarfish...If anything, it is a shovelnose guitarfish. Still a cool animal though!
