Habits Feeding Breeding The major part of the stingray's diet consists of worms, carrion, squid and crustaceans. The stingrays' mouth is on it's underside of it's body, which enables it to dig crabs and shrimp out of the sea bed. The stingray's teeth are primarily used for cracking the shells of it’s prey. Some rays lay eggs while others reproduce giving birth to live young that develop in the womb without a placenta. Fertilization is always internal. Rays have a long gestation period and produces relatively few young compared to other fish. The growth of ray populations, therefore, is slow.
