Amphibians
Amphibians as a group are often confused with reptiles, but they are their own distinct and separate group of animals. Amphibians are separated into three groups; salamanders and newts, frogs and toads, and caecilians. Amphibians are considered cold blooded. You may also hear the terms poikilothermic or ectothermic. These terms are usually used as synonyms for cold blooded. All of these terms mean that these animals can not regulate their own body temperature like birds and mammals. This means that if it's 85° where the amphibian is, then that amphibian will have a body temperature of 85° as well.
