Why do snakes shed their skin? Snakes shed their skin to grow and stay healthy. As they grow, their old skin becomes too tight and worn out. Shedding allows them to replace it with a new, larger one. This process, called ecdysis, helps remove parasites and other harmful substances. How often do snakes shed their skin? Young snakes shed more frequently, about every few weeks, while adults shed a few times a year. Factors like species, age, and environment affect the shedding frequency. What happens during shedding? The snake's skin becomes dull and its eyes turn blue, indicating it's ready to shed. It then rubs against rough surfaces to start peeling off the old skin.
