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.

Shovelnose Guitarfish (Rhinobatos productus)

The Shovelnose Guitarfish or Rhinobatos productus is just one of the many different kinds of Guitarfish. As you can see, they get their names from their guitar-shaped bodies. They have flat compressed bodies and are normally found on sandy bottoms less than 40 feet or so. Their bodies are brown or olive with white on the bottom. This coloration helps them blend into the sand where they lay and wait for their prey. In fact, Shovelnose Guitarfish will bury themselves in the sand with only their breathing holes exposed. The poor unsuspecting prey won't realize anything until the sand erupts and bye-bye prey. You can see them bury themselves in the video below...

The Shovelnose Guitarfish's mouth is located on it's bottom, although this fish doesn't actually breath through its mouth. Instead they have a holes on the top of their heads called spiracles that they use to breath into their gills.Female Shovelnose Guitarfish give live birth like sharks. The mating normally occurs in bays in California and Baja. If you have any more information about the Shovelnose Guitarfish that you would like to share please leave us a comment...
