Sharks are carnivores. They eat all kinds of flesh. Sharks prefer tuna, mackerel and even smaller sharks for dinner, but they will eat swimmers if the conditions are right.
Sharks have very sharp senses of vision, hearing and smell to help them find food. They can see seven times better than human and can hear sounds over two miles away. About two-thirds of a shark’s brain is used for smelling, so if there is even a tiny amount of blood in the water, a shark will smell it even if it’s almost a mile away
Instead of bones, sharks have something called cartilage. Bones are hard and don’t bend. Cartilage is flexible, allowing sharks to bend so their heads can reach their tails. The cartilage also allows sharks to turn very quickly. All this makes them better hunters. Humans have cartilage too, but only in places like our ears and noses.
