What are the prey and predator of a blue whale?
Diet: tiny fishes, krill, plankton, marine invertebrates
Enimies: some sea creatures including fish that hunt in packs
Neither. The blue whale eats krill or shrimp, and it's too big to be prey to any animal. but if you include humans then yes. the blue whale is prey, humans hunt it down for too many reasons. No. Don't listen to the silly rubbish above, krill are animals that the whales prey on. They are hunted or used to be by us and the calf's are sometimes attacked by orcas.
