Do snakes have scales or feathers?
Reptiles have scales. Scientists had previously found placodes on the embryos of birds and mammals, where they develop into feathers and hairs, but had never found the spots on a reptilian embryo before. The apparent lack of placodes in present-day reptiles fueled controversy about how these features first formed.
What class of animals have scales?

Why do snakes have scales on their bodies?
Because of this, snakes rely on their scales for protection for more than just exposure to UV rays from the sun. A reptile’s scales also protect the animals from abrasions as they scurry across the ground, climb trees, or briefly dive beneath the surface of the water.
Where do you find feathers, scales and scales in reptiles?
“We found the anatomical placodes” in reptile embryos, from snakes to lizards to crocodiles. Placodes (spots stained in dark blue by the expression of an early developmental gene) are visible before the development of hair, scales and feathers in (from left to right) the mouse, the snake, the chicken and the crocodile.
What makes a baby snake different from an adult snake?
Another difference is that even the smallest of baby snakes have scales. They don’t hatch from their eggs without scales, like certain animals don’t have fur or feathers while juvenile. The only difference is that the scales are small, albeit still visible. These scales are, biologically, a modified form of fur.
