SPERM WHALE
The sperm whale is the world’s largest predator. Its
jaw is longer than a car and each tooth is bigger than
an ice cream cone. Sperm whales dive very deep in the
ocean to prey on giant squid. Like all hunters, a sperm
whale needs to be clever to catch its prey. Not even the
blue whale—the biggest animal of all—has a larger brain.
