| | Choosing an Amphibian |
 | | Amphibians are divided into the salamanders, all of which have tails, some 400 species; frogs and toads, which are tailless, some 400 species; and the Caecilians, which have tails but no legs, 155 species, only one of which, the “rubber eel” appears in the pet trade. |
 | | Amphibians range in size from a Brazilian frog that, at 1½ inches long, is the world's smallest four-legged animal to the 145-pound Chinese giant salamander, the largest amphibian, which approaches 6 feet in length. |
 | | Salamanders have a keen sense of smell, using it and their quick and agile movements to find and capture prey. |
