Many sharks attack humans, but the big three are the bull shark, tiger shark, and great white shark.
All sharks
one for food two because they are harmful so they kill the shark to keep from the shark killing a human......????????
They are either hungry or feel threatened.
At the top -only humans hunt/kill them.
plane crashes yes not sure about the shark one thoughdonkeys kill on average 8,237 humans per year
Sharks aren't normally prey, but things that will kill a shark are humans and other sharks.
Dolphins, other sharks, probaly some whales, crocodiles, hippos, and humans can.
sharks have more to fear from humans
a whale shark
They are not really protected by anyone. Except if they were in a wild life water park or something then they would be protected by humans. And by the way dolphins gather together to make a circle around a shark if they were attacked by one, and kill it!!!BY: MTSbefore the kill the shark, they will ram their hard snouts into the shark's soft underbelly.
A squid can kill a shark. Depending upon the size of the squid, and the size of the shark, the squid can also eat the shark.
