Sting rays eat tuna ,small squid , and they eat jellyfish
What Does Stingray Eat?
Stingrays eat a wide variety of sea creatures including anything from plankton to crabs.
Blue ringed octopus
They eat small animals like crabs, clams, oysters, etc., and I have also been able to feed them shrimp and anchovies at stingray petting tanks. It's possible for them because they don't have teeth; they have dental plates, which they use to crush their food after sucking it up into their mouth.
Crab
A stingray eats insect larva a squid and as their diet they eat medium sized shrimp and crab
The last stingray I had ever dealt with ate small squid, but there could be other things they eat. It would be wisest to ask someone who actually feeds them.
These animals are predators, and they eat all types of plankton and also fish, that they catch near or upon the bottom of the ocean or rivers. Plankton consists of any drifting organisms (animals, plants, archaea, or bacteria) that inhabit the pelagic zone of oceans, seas, or bodies of fresh water.
Well, I think stingrays eat clams, fish, oysters, crabs, and etc,etc,etc...
