Adult frogs do not have tails and caecilians have only very short ones. [69] Didactic model of an amphibian heart. Salamanders use their tails in defence and some are prepared to jettison them to save their lives in a process known as autotomy. Certain species in the Plethodontidae have a weak zone at the base of the tail and use this strategy ...
Paleontologists have discovered a previously unknown ancient species: Kermitops — an amphibian that predates the dinosaurs and reveals the complexity of frog evolution. Researchers found a tiny ...
