摘要

PANGOLINS are a smuggler's dream. For defence, and when asleep, they roll themselves up into spheres, scales on the outside, to thwart any predator. That makes them easy to handle and pack. And handled and packed they have been, in enormous numbers. The International Union for Conservation of Nature, a worldwide wildlife-preservation organisation, reckons that more than 1m pangolins were traded illegally from their African and Asian homelands over the decade to 2014. That may be a conservative estimate. A paper published last year in Conservation Letters calculates the number of pangolins hunted in central Africa alone as between 400,000 and 2.7m a year. Based on statistics such as these it seems likely that pangolins, of which there are eight species, four African and four Asian, are the most trafficked type of animal in the world.
