The salamander is an heraldic monster, an elemental fire-spirit. In period heraldry, it’s usually depicted as a lizard enflamed; the illustration is taken from the badge of Francis I of France, c.1540 [Dennys 193].
The salamander is statant by default. Note that flames are part of the monster’s definition. If depicted without flames, it must be blazoned as a “natural salamander” and treated as though it were a lizard.
