Description

Excerpt from The Amphibians of Western North America: An Account of the Species Known to Inhabit California, Alaska, British Columbia, Washington, Oregon, Idaho, Utah, Nevada, Arizona, Sonora, and Lower California Reptiles. In fact they are neither fish, flesh nor fowl. Most amphibians lay their eggs in water, and the young, for a time, breathe by means of gills. After a metamorphosis, during which the gills and other larval characteristics disappear, the young assume the form and structure of the adults and leave the water to spend a greater or less portion of their lives on land. Reptiles never lay their eggs in water, and their young are hatched or born with the form and structure of their parents. The skin of 'our amphibians often is moist or slimy, and is not covered with scales. Many embryological and anatomical differences between amphi bians and reptiles exist but need not be stated here.
