Slow Loris (Nycticebus coucang), northern Sumatra, Indonesia
Native to Indonesia, the slow loris is being hunted into extinction, thanks to the supposedly medicinal and spiritual qualities of its flesh. But eager trappers had better watch out: the slow loris is also the world’s only venomous primate. It keeps its poison in a sac near the elbow, which it sucks out and reportedly swirls around in its mouth before delivering a dangerous bite.
