According to the wildlife trade monitoring organization—TRAFFIC， about one million pangolins （穿山甲） were killed from 2000 through 2013， mainly for their scales （鳞片）， which are used in medicine. Pangolins are sensitive creatures and picky eaters that only eat certain kinds of ants， a diet that’s very difficult to copy in the food chain.

“In the last decade， there’s been a huge growth trade in pangolins between continents， especially their scales，” says Dan Challender， chair of the pangolin specialist group. Previously， most pangolin killing happened within Asia， he says. This change means that Asian pangolins are becoming difficult to find but that the value of the scales makes it worth the extra cost to take pangolins from Africa to Asia secretly.

All eight types of pangolins， four in Africa and four in Asia， are in danger of extinction due to the illegal trade. International trade in the four types of Asian pangolins has been banned （禁止） since 2000. In the past few years， a ban on international commercial trade in all eight types has gone into effect. It was voted by 183 governments that are parties to the Convention on International Trade in Endangered Species （CITES）， which is in charge of cross-border trade in wild animals and their parts.

Pangolins are eaten as bushmeat in western and central Africa and by some local groups in South and Southeast Asia. Their parts also are used in Ghana， Nigeria， South Africa， and elsewhere in sub-Saharan Africa as traditional medicine. But they are now endangered. Perhaps no pangolins can be seen when our next generation grow up.

C. They eat all kinds of ants. D. They are at the top of the food chain.

2. Why are pangolins brought from Africa to Asia？
