PREDATORS
Other than humans, sharks really aren’t afraid of anything. It is a misunderstanding that sharks are afraid of dolphins. Dolphins will fight a shark and even kill it to protect their young, but other than that, they live very peacefully in the waters together.
DIET
Carnivore (Meat eater)
Great Whites are known to be the biggest predator on earth, as far as fish are concerned. They will eat sea turtles, sea lions, seals and carrion (dead animals). There are times that you can see a shark attack its prey from underneath it. Sharks have also known to breach, which means that they are moving so fast that they come out of the water to get its prey.
BABIES
Females will migrate to warmer waters in order to give birth to their babies, during the fall season. They are considered ovoviviparous, which means the eggs develop inside the mom until they are born. The pups have very strong jaws within the first month after birth. The stronger pups will eat the weaker pups. They are usually born in the spring and summer months. They are on their own from birth
