Why do snakes shed their skin?

Snakes shed their skin through a process called ecdysis to accommodate growth, as their skin does not stretch. This periodic shedding helps them maintain healthy skin, remove parasites, and heal minor injuries. The old skin becomes dull and dry before shedding, and snakes often use rough surfaces to aid the process. Younger snakes shed more frequently than older ones, and factors like temperature and humidity influence shedding cycles. This adaptation highlights their remarkable biological resilience.
