Classification

1. Amphibians are animals that fall under the category of amphibia.
2. They are capable of both terrestrial and aquatic life (aquatic).
3. As a result, they can breathe through their skin, lungs, or gills.
4. Two auricles and one ventricle make up the amphibian heart.
5. The number of chambers in a vertebrate heart determines how it is classified.
6. For example, sawfish and Trygon have two-chambered hearts with one ventricle and one atrium.
7. For instance, reptiles and amphibians have three-chambered hearts with one ventricle and two atria.
8. Crocodiles are the one exception, though.
9. They have a four-chambered heart.
10. For example, mammals and birds have four-chambered hearts with two ventricles and two atria.
