Amphibians

Amphibians are inhabitants of the magical swamp-like tropical world of Amphibia.

Description
Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems.

Appearance
The Amphibians look like anthropomorphic amphibians with four fingers and two toes, and many different colored bodies, eyes, mouths, and tongues. In the series, some amphibians have three different pupil shapes: realistic, semi-realistic, and dots. In the show so far, only Class Anura (Frogs and Toads) and Class Caudata (Salamanders, Newts, and Axolotls) have been shown. In Wartwood Swamp, their clothes are ragged, except for the Mayor and Toadie.

Anura (Frogs/Toads)
Most of the characters in this series have been frogs, (toads are a group of frogs.) including The Plantar Family, Sadie Croaker, Mayor Toadstool, Grime, etc. They have large eyes, retractable tongues, large rear feet, and two nostril holes for a nose. They are usually short and feature no tail. In the show, the toads are the ruling class of Amphibia and hold every position of power. Toads are more distinguished in the show as being more stockier, bigger and possessing groves that run parallel down their necks.

Anura children are alternatively called babies and pollywogs.

Caudata (Salamanders)
There have only been a few Salamanders (axolotls and newts are a group of salamanders) in the series so far, most notably Leopold Loggle and Albus Duckweed. They are similar to order Anura, but with many differences. Excluding a few frog species, salamanders have longer snouts and a tail.
