Amphibians
Amphibians (Lissamphibia) include fascinating creatures such as salamanders, newts, caecilians, frogs, and toads. These animals' ancestors were the first to venture out from the water and adapt to life on land. Amphibian larvea are often aquatic and go through a complex metamorphosis process as they grow to adulthood. They have moist skin and do not have scales, feathers or hair.
Making the Transition from Water to Land
The vertebrates that underwent the evolutionary transition from life in water to life on land faced four basic adaptive challenges.

Redefining Amphibians
I've been reading quite a bit recently about the stage in vertebrate evolution when early amphibians first colonized land. It's an intriguing time in Earth's history.

Why are Amphibians in Decline?
In recent years, scientists and conservationists have been working to raise public awareness of a global decline in amphibian populations. Herpetologists first started noting that amphibian populations were falling at many of their study sites in the 1980s.
