No they do not.
yes great white sharks eat other sharks
Sharks aren't normally prey, but things that will kill a shark are humans and other sharks.
Of course they can kill each other. Humans and sharks are enemies.
no because dolphin can't kill shark
sharks
Sometimes.most of the time some sharks will attack for no reason .they like to feed on blood by other organisms.other times sharks will mistake us for fish and kill or eat people.
no they do not eat sharks because a shark is to big for them to eat but they can kill sharks
If they kill other animals for food then, YA they are! :)
about the only predator is people. unless that is you count dolphins believe it or not they are know to gang up on sharks and kill them.
Sharks are apex predators. They do not have any natural predators except other sharks. Large sharks are known to kill and eat smaller ones.
It depends. Sharks are usually afraid of people. unless you get on their bad side Sharks and other predators are not "mean" - it is in their nature to hunt and kill other animals.
No, sharks kill more.
