There are slight variations of the numbers of rays in the anal fin of the big three catfish species and other minor physical differences. The torpedo or electric ray has no stinger, but does possess electric organs capable of pro-ducing a shock.

The transformation from caterpillar to butterfly is such a complete metamorphosis that the butterfly, which may have started out life as a stinging, biting caterpillar, has absolutely no ability to sting or bite because the stinging parts and … The new one grows underneath the old ones.” – Dr. Christine Bedore Contact with the stinger causes local trauma (from the cut itself), pain, swelling, muscle cramps from the venom, and later may result in infection from bacteria or fungi.

Cownose rays have poisonous stingers, but even in large groups they’re shy and not threatening. "Through evolutionary history, they have lost their stinger," says McCombs, "but developed several other unique adaptations, including the cephalic lobes (specialized flaps on the front of their face that help them to filter tiny plankton from the water)." 8-They often visit sites called “cleaning stations” where some fish species are responsible for removing parasites from their skin. 6-They do not represent a significant threat to humans, but may attack if disturbed.
