Have you ever heard of the lesser blind mole rat (Nannospalax leucodon)? Growing up to 10.6 in (27 cm) long, this rodent can be found in parts of Eastern Europe. A nocturnal animal, it spends the majority of its life underground, digging long tunnels beneath the surface. Though you might think that this species is completely blind, it actually isn’t. This critter’s tiny .04-in- (1-mm-) eyes, which are hidden beneath its fur, help it sense light and navigate its underground habitat.
