Many people believe sharks are dangerous and always try to hurt or even kill humans. In fact, 94
percent of the world"s 400 species (种类) are harmless to humans. Shark Exhibition at the National
Aquarium (水族馆) in Baltimore in the US proves this. Visitors can touch young sharks, see their eggs
develop and watch a dozen different species swim smoothly around a huge tank.
Most people don"t know that shark attacks don"t happen very often. Humans are more likely to be
killed by lightning (闪电 ) than by a shark. And to make this point clear, the museum has set up a
special touching pool for children. There kids can learn, from an early age, not to be afraid of sharks.
They can watch them develop inside their eggs and feel the skin of the older sharks.
"People are afraid of what they don"t know," said Nancy Hotchkiss, an organizer of the exhibition,
"Sharks have been around for 400 million years and play an important role in the ocean"s food chain
(食物链). We want people to discover that sharks are amazing animals that need our respect and
protection. "
About 100 million sharks are killed every year around the world by humans. Thousands of sharks are
hunted in Asia for special food, and many others are caught in nets. when fishermen are hunting other fish.
It is a worrying situation that some countries have not put measures (措施) to protect the special fish.
