How much do you know about flying squirrels? Many people living in regions with heavy flying-squirrel populations have never even heard of flying squirrels. But that is fair; after all, flying squirrels are nowhere near as exposed to the public as squirrels are. Flying squirrels are the only mammals that can fly. Well, actually flying squirrels glide, but they don't necessarily fly in the strictest sense of the word. Flying squirrels are known for their ability to glide from tree to tree, but it can be difficult to spot a flying squirrel tree-hopping in the wild. Flying squirrels are noted for their bizarre eyes. Their eyes are big and round, and they look to be bugging out a bit. Other regular squirrels, on the other hand, have small eyes since the visual sense is not as paramount to the squirrel's survival as it is with the flying squirrel. The flying squirrel needs it's complicated eye anatomy and the acute vision that they are endowed with in order to see through forests and jungle areas at night, after all, flying squirrels are nocturnal creatures. Flying squirrels live on three different continents but they are not evenly distributed. Forty of the forty three different flying squirrels species are found on the continent of Asia. So Asia has ninety percent of the flying bat population living there. Most all of these Asian flying squirrels are endemic to the region, which means that these unique flying squirrel species do not exist anywhere in the world except for Asia. Sadly, these Asian flying squirrels are currently under threat from the booming forestry business in Asian countries. However, past research has shown that flying squirrels can survive even the most calamitous of environmental pressures. Have you ever spotted a flying squirrel while visiting an Asian country?
