New Bowmouth Guitarfish Arrive at the Georgia Aquarium

Aquarium participating in cooperative study of the reproductive biology of bowmouth guitarfish

Atlanta (November 13, 2007) – Georgia Aquarium introduced a male and female bowmouth guitarfish into the Ocean Voyager exhibit on Tuesday, Nov. 13, 2007. The male is approximately 6.5 feet long, and the female is almost five feet long. These unique fish, who receive their name from their guitar-shaped bodies, are housed in only a few facilities in North America. They are often referred to as shark rays because of the combination of physical characteristics from both animals. Georgia Aquarium will be participating in a national and international cooperative study of the bowmouth guitarfish reproductive biology. The animals recently arrived from Taiwan and are listed as vulnerable by the IUCN due to overfishing and habitat destruction.

About the bowmouth guitarfish The bowmouth guitarfish (Rhina ancylostoma) is found throughout east and southeast Asian waters, the Indian Ocean and the Red Sea. This distinctive animal is grayish-brown in color with white spots on its dorsal (top) fins and black spots on its head and shoulders. The anterior part of the body and the large dorsal fins create a shark-like appearance. It has a broad rounded snout and a heavy ridge of spiky thorns present above the eye, along the back and on the shoulders that are used as a defensive function. The bowmouth guitarfish is ovoviviparous, meaning it produces eggs that hatch in the female’s body. Its jaws are heavily ridged, with crushing teeth in undulating or wave-like rows, and it feeds mainly on bottom crustaceans and mollusks like shrimp, crabs, and clams.
