1. Amphibian
This refers to a class of vertebrate animals that spend part of their time on land and part in the water; they are an intermediate form between fishes and reptiles. Amphibians must return to the water to breed and they have distinct larval and adult forms. Members of this class include frogs, toads, and salamanders. This word is derived from the Greek word amphibios, which means "living a double life".

2. Amphibians
Class of terrestrial vertebrates which lay their eggs (and also mate) in water but live on land as adults following a juvenile stage where they live in water and breathe through gills. Amphibians were the first group of land vertebrates; today they are mostly restricted to moist habitats.
