Southern Stingray (Dasyatis americana)
The Blue-Spotted Stingray (Taeniura lymma), which prefers to hide in the sand around coral heads and rocks, is often spotted by its blue-striped tail. These rays travel in groups as the tide rises to feed on mollusks, crabs, shrimp, and worms.
With a wingspan of up to three meters, the Spotted Eagle Ray (Aetobatus narinari) is a giant beauty. Unlike most other rays, the spotted eagle ray is a very active swimmer. Most of its swimming time is spent in open water, although it is also commonly seen inshore. These rays are very agile and can twist and turn to escape predatory sharks. Sometimes, small groups splash around at the surface, making spectacular leaps out of the water.
Fish experts believe the giant stingray, such as this one in Cambodia’s Mekong River, is the largest freshwater species on Earth. This specimen measured more than 13 feet (4 meters) long.
