What kinds of enemies does a great white shark have?

Answer 1

Adult Great Whites are apex predators. Apart from the Orca (Killer Whale), there are no known predators that may attack or kill a Great White. In regions where both the Orca and the Great whites inhabit and compete for food, Orcas may attack and kill these sharks. Since Orca's are much larger than them, they can attack and even kill great whites. Apart from this, Human hunting is the single biggest threat to these sharks. Humans have hunted these sharks for decades due to fear and general game hunting. They are classified as "Vulnerable" which means that, if we don't take steps to protect this species, they may go extinct soon.

Answer 2

Killer whales have been known to attack and kill great whites. There is a recording of a killer whale killing a great white of the coast of California
