Shark attack is when a big fish with sharp teeth called a shark bites a person who is swimming in the ocean. Sharks live in the ocean and sometimes they think people are fishes or other things they like to eat, and they bite them by mistake.
Not all sharks are bad, in fact most of them are not interested in people at all. But some sharks are dangerous, and it's important to be careful when you are swimming in the ocean.
If a shark bites a person, it can be very scary and painful. It can also cause a lot of damage and even be deadly. That's why it's important to avoid shark-infested areas, and if you do go swimming in the ocean, do it with a group of people and stay close to shore.
If you do get bitten by a shark, it's important to get help right away. Call for help and try to stay calm. If you can, try to stop the bleeding by putting pressure on the wound. Remember that shark attacks are very rare, and if you are careful and follow the rules, you can enjoy swimming in the ocean without worrying about them.
