Types of amphibians include frogs, toads, salamanders, newts and caecilians. Amphibians are distinct because they live their lives both in water as fully aquatic larvae and at least partially on land as adults.Continue Reading
Caecilians are the least known of the amphibians. They're also called blindworms because they usually live underground, where sight is useless. They live in the tropics and are legless, which gives them the appearance of large, slimy worms. Though some caecilians reproduce like most other amphibians and lay eggs in water or damp places, others give birth to live young.
Salamanders resemble frogs except that they have long tails. Salamanders that are called sirens only have forelegs and look somewhat like eels, though they have both lungs and gills. Some salamanders are in fact lungless and gill-less and breathe through their skin. Newts spend most of the time living on land, and their skin tends to be dry and bumpy. However, like all amphibians, they need to keep their skin moist, so they can't be far from a watery environment for too long.
Frogs and toads are a very diverse group of amphibians. In general, toads are squat and warty, while frogs are a bit more slender and have smooth skin. Frogs and toads live just about everywhere on Earth except for the most inhospitable climates.Learn more about Amphibians
