Book excerpt: Excerpt from The Reptiles of Western North America, Vol. 1: An Account of the Species Known to Inhabit California and Oregon, Washington, Idaho, Utah, Nevada, Arizona, British Columbia, Sonora and Lower California' Lizards The term reptile is popularly applied to all cold-blooded vertebrates other than fishes. Thus used, it includes two groups of animals which differ in many important respects. These are the amphibians and the reptiles proper, the former more closely, allied to the fishes; the latter, to the birds. The typical amphibians, such as most frogs, toads, sala manders, and newts, lay their eggs in the water, and the young, for a time, breathe by means of gills, very much as do the fishes. Later on, they undergo a metamorphosis, during which the gills and other larval characteristics dis appear, the tadpole assumes the form and structure of its parents and emerges from the water to breathe air and spend a greater or less portion of its life on land. The skin of our amphibians is not provided with scales, but is smooth or warty, very glandular, and Often covered with a slimy secretion.
