Ke-Re Reef

This tropical reef offers guests a chance to see and feed several species of stingrays. Despite the name stingray, these animals are as harmless as they are mesmerizing. Rays are more than 500 species of flattened fish that are closely related to sharks. Rays and sharks have skeletons made of cartilage (like in your nose and ears) instead of bone and breathe through five or six gill slits. Rays slowly swim above the seafloor, searching for clams, crabs, shrimps, squid, and fishes hidden in the sand. They use suction to pull prey into their mouths and then crush through any hard shells with rows of flattened teeth.
