Habits

Feeding

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.

Breeding

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.

How many are there?

98 different species found so far

Statistics5,000 stingray attacks are reported

each year in the United States.

There have now been two deaths reported in Australia after the barb
