What physical trait provides the rough and spiky texture of the Candoia aspera?

Answer

Keeled scales

The rough, spiky skin of the Viper Boa is caused by keeled scales, which feature a distinct ridge running down the center of each scale. This feature is a primary component of the snake's physical mimicry, causing it to resemble dangerous, venomous species, and the scientific name aspera refers directly to this rough tactile quality.
