am·phib·i·an

(ăm-fĭb′ē-ən)
A cold-blooded vertebrate animal having moist skin without scales. Most amphibians lay eggs in water, and their young breathe with gills but develop lungs and breathe air as adults. Amphibians include frogs, toads, and salamanders.
Word History Amphibians are not quite fish and not quite reptiles. Like fish, they spend part of their lives living in water and breathing with gills; like reptiles, they usually spend another part of their lives breathing air with lungs and able to live on land. This double life is also at the root of their name, amphibian, which, like many scientific words, comes from Greek. It is made up of the Greek prefix amphi-, meaning "both" or "double," and the Greek word bios, meaning "life." Both these elements are widely used in other scientific words in English: bios, for example, is also seen in words like biology, antibiotic, and symbiotic.
reptile, amphibian - A reptile has dry, scaly skin, while an amphibian has moist skin.
