What are stingrays? Like sharks, stingrays belong to a class of animals called elasmobranchs, which are characterized by their boneless skeletons made of cartilage — the same semi-flexible protein that gives shape to human ears. The stingray's flat body allows it to sit on the bottom of the ocean, river or lake, camouflaging itself to predators swimming above as it hunts its prey on the floor. Its eyes sit on the top of its body, while its mouth is on the bottom. Stingrays have tails which often have a serrated, toxin-filled barb. If a stingray feels threatened, it can lift its barbed tail upward and injure potential predators. #61stpier #pierfishing #stingray #lovegalveston
