All sharks
Many sharks attack humans, but the big three are the bull shark, tiger shark, and great white shark.
one for food two because they are harmful so they kill the shark to keep from the shark killing a human......????????
A shark can kill both. A piranha may be fast and have lots of teeth, but so does a shark. And many sharks are cannibals, meaning they will eat their own kind.
They are either hungry or feel threatened.
At the top -only humans hunt/kill them.
Sharks aren't normally prey, but things that will kill a shark are humans and other sharks.
Well, in logical and obvious terms, no of course not! The Tiger Shark is an extremely dangerous shark. Most sharks eat meat. Humans are meat. A Tiger Shark can be kind, but only in your imagination sorry. :) From and thanks, -ThehorseGal&Advisor sharks dont often eat humans
Bull Sharks are apex predators. In their natural habitat, they have very few natural predators. Very few marine animals are large enough to actually hunt or kill a full grown bull shark. However, humans are the biggest enemies for these sharks. They have been hunted and killed indiscrimenately by humans for decades.
Dolphins, other sharks, probaly some whales, crocodiles, hippos, and humans can.
sharks have more to fear from humans
plane crashes yes not sure about the shark one thoughdonkeys kill on average 8,237 humans per year
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.
