Salamanders are distinguished from other amphibians (frogs and caecilians) most obviously by the presence of a tail in all larvae, juveniles and adults, and by having limbs set at right angles to the body with forelimbs and hindlimbs of approximately equal size (except in the family Sirenidae, which lacks hindlimbs).
