Prairie dog burrows provide the nesting areas for mountain plovers and burrowing owls. Species can be arboreal, fossorial (burrowing), or semiaquatic. Like other badger species, European badgers are burrowing animals. Generally, vision is best in arboreal snakes and weakest in burrowing snakes. They are more exposed to attack by predators than the burrowing bivalves. Subterranean species evolved bodies streamlined for burrowing, and eventually lost their limbs. Some frogs have become adapted for burrowing and a life underground. Mammals are perhaps most well known for burrowing. They are often attracted by the dung collected by burrowing owls. They also create a habitat or temporal shelter for many burrowing and benthic organisms. Burrowing mites are in the family Sarcoptidae. Cape Coral is home to the largest population of burrowing owls in Florida. All are fossorial (adapted for burrowing). Whiskers themselves may have evolved as a response to nocturnal and/or burrowing lifestyle. The Foxes manage to escape by burrowing further beneath the earth to safety.
