Of all of the felines, the Margay is most adapted for a true arboreal life. It is the only cat to possess the ability to rotate its hind legs 180° , enabling it to run head first down trees like squirrels. It can also hang from a branch by one hind foot!
The Margay is on the endangered animals list, but no one really knows how large their population really is between Mexico and Argentina. Margays don’t take well to humans invading their habitats and sacientists say they are so well adapted to life in trees that they can go their entire lives without touching the ground.
