Does the tadpole have a tail? The tadpole? The caudal fin is remarkably fragile – just a double layer of skin with no skeletal support. Yet, despite being about as easy to tear as wet tissue paper, the caudal fin is stiff enough to provide thrust as the tadpole swims.
Where does a tailed frog live? Tailed frogs live in and beside cool, clear mountain streams with year-round flow. All stages from egg to adult can only tolerate a narrow range of water temperatures. The eggs are the most sensitive and can only survive in streams with highly oxygenated waters and temperatures of 5 to 18 degrees.
