Salamander

Salamanders of the Narnian world were dragon-like reptilian sentient beings that lived only in the lava rivers of Bism. (In Earth, salamanders are a type of amphibian.) They lived far beneath the Narnian earth and were too white-hot to look at, sharing their habitat with flowering gems and the Earthmen. Salamanders were wonderfully clever with their tongues since they possessed the ability of speech and were very witty and eloquent.

During the last day of Narnia, salamanders were also assisting the dragons in destroying the world of Narnia.

Trivia

"Salamander" is Greek for "fire lizard", and these creatures are associated with fire in several legends.
