How is the scale texture of a whiptail lizard typically described, aiding its streamlined profile?

Answer

Smooth rather than keeled or rough

Beneath the superficial impression of smooth skin, whiptails are actually covered in scales. However, the texture of these scales is generally characterized as smooth, distinguishing them from species possessing keeled or rough scales. This smooth surface texture is advantageous as it aids in maintaining a streamlined profile, which is essential for reducing drag and achieving their impressive bursts of speed.
