Grown White Shark Monterey Bay Aquarium Can't A Full Grown Great White Shark Kill An Adult Orca ?

Can't a full grown great white shark kill an adult orca ? - grown white shark monterey bay aquarium

I have many people say that white sharks deserve their reputation as wild. Great whites vary with its weight and its hard to tell what is real. And I saw an orca killing 10 whites and big feet, and I know adult white sharks kill adult killer whales had been seen to? I want concrete evidence that will see them?
