Sharks have often attacked people who have survived shipwrecks or plane crashes far out at sea. Inflatable bags have been tested, which sharks tend to avoid. They can’t detect moving limbs, electrical signals or blood inside them. Beaches can be protected by nets.
Is it true? Nothing attacks a shark.
No. Sharks will attack each other. They are also attacked by whales, and even dolphins who will group together to protect their young. But the biggest threat of all comes from people.
Amazing! In Australia in the 1930s, hundreds of sharks were caught in nets in just a few months. The numbers of many large sharks have gone down sharply all over the world because of hunting.
Who swims inside a cage?
Scientists studying dangerous sharks, such as the ocean white-tip and bull shark, often protect themselves inside a cage. The shark can bang the cage as much as it likes, but the diver is safe inside.
Why do sharks attack?
When a shark attacks, it is often because it mistakes a swimmer or surfer for a seal or other prey. About 100 shark attacks are recorded on people each year. Many of the victims survive.
