No, snakes do not breathe through their skin. Snakes, like most reptiles, breathe exclusively through their lungs. While some sea snakes, like the Hydrophis cyanocinctus, have evolved to absorb a small amount of oxygen through their skin, this is not their primary mode of respiration.
Snakes are air-breathing animals and rely on their lungs to take in oxygen and expel carbon dioxide. Their skin is covered in scales, which are impermeable to gases, preventing any significant gas exchange through the skin.
Some amphibians can breathe through their skin, but this is not the case for snakes. Amphibians have thin, moist skin that allows for gas exchange, while reptiles have dry, scaly skin that prevents water loss and is not suitable for breathing.
