Who are the predators of the gray whale?

Answer 1

Adult, healthy whales are large and powerful enough that the only predator that they need fear is man. Humans have hunted grey whales for millennia. Young, sick or injured whales could be food for sharks, orca, or any other large and fast oceanic carnivores.

Answer 2

Orca's are the only known natural predator of the gray whale. Groups of Orca's can easily kill a mid sized gray whale. Full grown adults are too big for even a group of Orca's to kill. But, babies are especially vulnerable. The Gray Whales give birth to their young in shallow lagoon waters. This is done to protect the newborn from predators like sharks and orcas

Gray Whales feed on benthic crustaceans that are found on the sea bed. The whale scoops up sediments from the sea floor and filters out edible particles and feeds on them. Crustaceans like Krill, small lobster, shrimp etc would form the food chain of the gray whale.
