Can a great white swallow a seal?

It is impossible tofr a Great White to eat a sperm whale. Sperm Whale is just too big and too powerful for any shark. An adult Sperm whales is upto 67 feet long and weighs upto 57 tons. Grate white is not even a third of the size. No animal goes against someone three times its size. Also, sperm whale is one hell of a smart animal. It can dive at the depths that would crush a shark to death.

Sharks probably eat whales of all kind but only after the whales are dead.
