    Pangolins (穿山甲), the world’s only mammals with scales (鳞片), have existed on earth for about 60 million years. Pangolins are very sensitive creatures and most of them don’t like staying indoors. In the wild, they’re slow to reproduce and give birth to only one baby at a time. Pangolins are alone and shy — nearly impossible for even the most devoted field researchers to catch sight of.

However, over recent ten years, their wild population has decreased greatly. More than a million pangolins are believed to have been taken from the wild in Asia and Africa. In the first eight days of April 2019 alone, authorities caught two 14-ton shipments of pangolin scales in Singapore, representing about 72,000 animals and worth a combined $90 million. In February, Malaysian seized a 33-ton shipment of mostly whole, frozen pangolins.

“The present scale of trade could drive this species to extinction,” said an Indian official.

If the illegal pangolin trade continues at such high levels, it’s thought that another 10 years might see them die out altogether. The trade is caused by a series of factors, but the fact that the local government doesn’t make strict laws against it plays a major role.

Another big challenge facing pangolins is that so few people know what they are and why they’re in such danger. As National Geographic Photo Ark photographer Joel Sartore says, “You won’t save what you don’t love.”
