Amphibian Fact Definition Characteristics List Of Types Amphibians are ectothermic (cold blooded) vertebrates that belong to the class amphibia. a defining characteristics is their ability to live both in aquatic and terrestrial environments. the term “amphibian” is derived from the greek words “amphi” (both) and “bios” (life), reflecting their dual lifestyle. they lack scales, instead. The meaning of amphibian is an amphibious organism; especially : any of a class (amphibia) of cold blooded vertebrates (such as frogs, toads, or salamanders) intermediate in many characters between fish and reptiles and having gilled aquatic larvae and air breathing adults.
What Is An Amphibian Definition Of Amphibian Amphibian | characteristics, life cycle, & facts. Amphibian amphibian. Amphibian definition. amphibians are cold blooded, vertebrate animals that have an aquatic phase of life (spent in water, breathing through gills) and a terrestrial phase of life (living on land, breathing with lungs). cold blooded means that an amphibian can’t generate its own body heat. instead, their temperature varies with the temperature. An amphibian is a tetrapod. as fish began to evolve into amphibians, a completely new type of animal body structure appeared. this new type of body had four limbs, and feet equipped with digits (toes fingers). animals with this type of body (and animals whose ancestors had this style of body) are known as tetrapods.
