The placental mammal order Carnivora encompasses many charismatic taxa, including dogs and cats, bears, raccoons, weasels, hyenas, civets, mongooses, seals, sea lions, and walruses. With over 260 living species, Carnivora is one of the most species-rich and ecologically diverse groups of mammals. Despite their name, carnivorans range in diet from pure carnivores to species that specialize on fruit, leaves, and insects, as well as the full spectrum of mixed diets. Carnivorans also display a broad range in styles of locomotion, from the fastest land animal, the cheetah, to climbing, burrowing, and aquatic species.
