The underbelly typically displays a lighter hue. Juveniles exhibit more pronounced patterns that fade with age.

This species is largely solitary, defending individual territories marked by scent. Adaptations for aquatic habitats include tail undulation for swimming and a vibrational communication method effective under water.
