Shark Life
What Sharks eat:
The food a shark eats depends on the place the shark is at the time but, most sharks are meat eaters so they feed off of other fish. Sharks will consume 2% of their own body weight. They can adapt to an enviornment pretty easily.
Sharks use their sharp teeth to chew up their food. They can grow up to 30,000 teeth in their lifetime.
The reason why sharks are fish:
Sharks are fish because they don't come to the surface for air like other mammals, they rely on their gills to breathe underwater.
