The Japanese Giant Salamander is the second-largest amphibian in the world, reaching lengths of 1.5 meters.
These amphibians have squat, rounded bodies with jaws as wide as their head.
These small frogs can be 2-3 inches in length with females being larger than males.
This small frog grows to about two inches long and is immediately recognizable for its brilliant green colors, amplified in intensity by a black background.
Like most Poison Dart Frogs, these animals only grow to be about two inches.
