The Ili pika is endangered. According to the International Union for Conservation of Nature, there are only 2,000 individuals left in its population and is believed to be decreasing. See, pikas are best suited to cold environments and can retain heat extremely well due to their small ears, short limbs, and a spherical (aka adorable) body shape. So well, in fact, that living at a temperature of 78°F for two days can kill it from heat exhaustion. Weidong Li, the scientist who first discovered it, is looking to create a conservation area to help the Ili pika build its numbers, but so far his efforts have been in vain.
