UNIT 1 SHARKS
Narrator: The great white shark is known for its size. The largest sharks can grow to six metres to length and over 2,000 kilograms in weight. Great white sharks are meat-eaters and prey on large sea creatures like tuna, seals and even whales. Great whites have also been known to attack boats. This researcher is lucky to escape with his life when a shark bites into his boat. Three people are killed on average each year by great white sharks.
