Frogs and toads live in a variety of habitats. but most prefer moist regions. Although they breathe air through lungs many can stay underwater for long periods, absorbing oxygen in the water through the skin. Tree frogs are adapted for tree livings: other anurans are permanently aquatic: still others spend most of their lives in underground burrows. coming up only to feed or breed. Like all amphibians. an anuran's body temperature depends on its surroundings. In colder regions, the animal burrows in mud to hibernate: some. such as Australian frogs. estivate lie in a state of torpor after burying themselves in sand or clay
