How do you count scale rows on a snake?

When scale counts are presented as xx-xx-xx: the first number is the number of scales one head’s length behind the head, the second is the number of scales at mid-body (halfway between rear of head and anus) and the third is the number of scales one head’s length in front of the anus.

What is the scale of a snake?

Why is the snake covered with dry scale?

Reptiles have a tough, dry, scaly skin that protects them from predators and allows them to live in dry places by reducing water loss. Reptilian scales are made of keratin, like hair, and found in an overlapping arrangement. This creates a sort of environmental shield for the animal.
