What is the primary function of the keeled scales found on the skin of the Green Vine Snake?
Answer
To reduce glare and shine under direct sunlight
The scales of this snake are keeled, meaning they feature a slight ridge running down the center rather than being smooth. This unique texture is crucial for breaking up the light that hits the snake's body. By minimizing the glare and reflective sheen that smooth scales would naturally produce, the keeled texture helps the snake maintain a matte, organic appearance that mimics a leaf or twig, effectively completing the camouflage necessary for survival in sunlight-focused concealment.
