What are scutes in snakes?

Scutes are specialized scales found in snakes that serve a significant role in locomotion. They are typically tougher and larger than the other scales covering the snake's body. Scutes provide traction and grip, allowing snakes to move efficiently across a variety of surfaces. This is particularly important since snakes often traverse different terrains, from rocky areas to sandy ground and even slick surfaces.

While there are other features like the sensory organs and color patterns that aid in survival, such as detection of vibrational cues or camouflage, those are not related to the specific structural adaptations provided by scutes. Additionally, breathing in snakes is facilitated by other anatomical structures, making scutes primarily associated with movement and surface interaction rather than respiratory functions. Hence, the correct answer accurately highlights the role of scutes in aiding snake movement.
