The order Caudata consists of approximately 500 species of amphibians known commonly as salamanders. The name originates from the Persian word sām meaning “fire” and andarūn, meaning “within.” Many salamanders are toxic, and its likely that this name comes from an understanding of their unpalatable nature.
Salamanders have four front toes and their hind legs have five. They have moist skin which usually makes them dependent on habitats in or near the water. Some salamanders find protection under logs or in the soil and gain their moisture from the ground. All species of salamanders lay eggs in the water. Unique among vertebrates, certain salamanders are capable of regenerating lost limbs, as well as other body parts, like fingers.
