The DWA exhibits an unusually extensive series of freshwater and saltwater stingrays. This inhabitant of coral reefs from the Red Sea to the Indo-Pacific is one of the most colorful of all elasmobranchs (sharks, rays, and chimeras). It is a small stingray, never more than three feet long, including its tail. It hunts crustaceans and other invertebrates.
The Spotted eagle ray is named for the spots on the dorsal side of its body, and for the way that it appears to “fly” underwater. It is also known as a Duckbill ray because of the unique shape of its nose which is used to locate its prey in sandy sediments. Spotted eagle rays can be found in large schools in bays or coral reefs, but spend a great deal of time in open water. When being pursued by a potential predator, it can be seen leaping from the water. The Spotted eagle ray possesses a venomous spine at the base of its tail and can inflict a serious wound. It is protected by law in the State of Florida, but is not considered an important commercial fisheries species.
While many of the 20 or so species of South American river stingrays have restricted ranges, this species is found in practically every river basin in South America. It is a popular species in aquariums because of its large orange spots. It can reach a diameter of two feet.
This species has a restricted range in South America, found only in the Xingu River Basin of Brazil, creating a concern that mining or other polluting activities could threaten it. Because of its striking pattern, it is highly valued for aquarium displays, and is now being captive bred around the world.
