Cannibal shark

Couldn’t find other shark thread so I put it here.

Is a great white shark a cannibal if it eats a black tip shark? Is a big mouth bass a cannibal if it eats a sun fish? Is a wolf a cannibal if it eats a dog?

That’s one big tangle the researchers have there. Researchers maybe but fishermen , no.
