What subtle feature do some taxonomic descriptions note regarding the dorsal scales of *Dendroaspis viridis*?
Answer
Dorsal scales can be weakly keeled
While the scales covering the body of the Western Green Mamba are frequently emphasized as being smooth, which assists in reducing friction against bark and minimizing snag potential while moving rapidly through foliage, some specific taxonomic analyses introduce a nuance. These descriptions sometimes note that the dorsal scales can possess a slight, subtle feature described as being weakly keeled. This minor variation in texture, contrasted with the generally smooth appearance, relates to the functional mechanics of movement for this arboreal specialist, contributing to the snake's speed and ability to navigate complex canopy environments effectively.
