Question

【题目】The next time you take medicine when you’re ill, you may eat a cone snail(芋螺). At least that’s what some scientists are hoping. Scientists have found that cone snails can help with backache, as well as toothache and other body problems.

There are over 600 different kinds of cone snails. This family is especially found in warm and hot waters in the oceans. They catch and eat small fish and even other cone snails. The snails have venom that they’ll give out and use to kill small animals they have caught because cone snails are slow-moving. Sometimes the venom can even kill people. But some scientists have discovered that the venom can also be used as medicine.

The shells of cone snails are often brightly colored, and have interesting shapes, many people think the shells are so beautiful that people kill them, collect lots of shells, and sell them around the world. The environment is also very dangerous for them because of fishing and boating.

Scientists want to help save the cone snails. They hope to make new rules to stop them from dying. If they die out, scientists may never discover what kinds of medicines they can give us.
