White-Blotched River Ray (a.k.a.
Leopoldi Stingray, Freshwater Stingray)
These rays eat small invertebrates and fish.
At The Toledo Zoo they start out as pups eating chopped up red worms and
black worms. Then as they grow they will eat chopped up frozen foods such
as small krill and mysids. As they mature they will take smelt, large
krill and worms.
They can grow to over 18 inches in diameter.
