The stingray as some know is one of the many dangerous creatures that lurk beneath the Pacific Ocean. The stingray when it strikes you not only puts poison in you but it can rip into the flesh.
Stingrays are invertebrates.  If they were an invertebrates they would not be able to cause as much damage as they would with a spine.
Stingrays eat clams, crustacean, and other invertebrates. They use their deadly instinct to kill their prey.
Some stingrays are in aquariums in museums and you can pet them but in there their rays are removed.  Just remember that in the wild they're more dangerous rays and all.
