SPERM WHALES AND SHARKS

They came after the dinosaurs

An episode from the series MYSTERIES OF THE GIANTS

Synopsis

The sperm whale and white shark have been ruling the oceans for millions of years. After the first few years of their lives, they have barely any predators.

Adult sperm-whale protect their infants and teach them to dive down into the depths where food is plentiful enough to allow them to grow to their huge size.

White sharks are born with predatory instincts and are as solitary as killer whales are social. They grow up near a coast before heading out to sea and becoming formidably efficient hunters.
