Despite the name, slot whale sharks aren't whales, they're a type of fish that qualify as absolute units of the deep. They typically chow down on krill, a type of small crustacean,
but scientists have discovered a previously unknown dimension to their diet: plants. That makes whale sharks the largest omnivores in the world.
Omnivores are animals (like humans and most bears) that eat and draw nutrients from both meat and plants. Whale sharks can grow to nearly 60 feet (18 meters) long. That's the length of a bowling lane.
