Why Do Snakes Shed Their Skin?

Did you know that snakes and trees have a shared gift? Snakes don’t stop growing until they die, and neither do trees. Snakes share this ability with some other animals like lizards and some amphibians, clubbed together in a category called “ indeterminate growers ”. In the case of trees, they don’t grow in height but grow in girth, much like a bodybuilder. However, trees don’t shed any bark as they grow. On the other hand, you may have seen snakes shedding their skin. Why do snakes shed their skin? And does it hurt? Let’s study this curious case.

Why do snakes shed their skin?

Before we go into the science, let me ask you a question. Do you still wear the same T-shirt that you got as a present when you were a toddler? The answer is probably no. By the time you hit double digits, your body has perhaps outgrown all the clothes you wore as a toddler.

Snakes outgrow their outer skin too. As a snake grows, it needs larger “clothes”, or in this case, a larger skin. However, you may wonder: It’s only a snake. They slither, eat, sleep, repeat. What’s the big fuss with tight skin?

As you will see, there’s a good deal of trouble that comes fleeting with tighter skin, even for an animal that slithers.

Why does older skin put snakes at risk?

Their growth is limited by the rigidity of their skin. As a snake grows, its old skin becomes tight and uncomfortable. To accommodate their expanding bodies, snakes must shed their old skin to reveal a new, larger one underneath. This allows them to continue growing and thriving.

Over time, a snake’s skin can accumulate damage from various sources, such as scratches, injuries, and infections. By shedding its old skin, a snake can remove damaged and infected layers, revealing fresh, healthy skin underneath. This process is akin to humans shedding dead skin cells, but snakes do it all at once in a more dramatic fashion.

Snakes, like all animals, are susceptible to parasites such as ticks and mites. These tiny pests can embed themselves in a snake’s skin and cause discomfort and health issues. Shedding the old skin is an effective way for snakes to rid themselves of these unwanted hitchhikers.

In the wild, snakes rely heavily on camouflage to hunt for prey and avoid predators. Their old skin can become dull and fade over time, reducing their ability to blend into their environment effectively. By shedding their skin, snakes reveal a fresh, vibrant, and more brightly colored skin that enhances their camouflage.

How often do snakes shed?

Snakes are highly adaptable creatures, and their shedding frequency can vary depending on environmental factors. Factors such as temperature, humidity, and food availability can influence how often a snake sheds its skin. And of course, the omnipresent need to grow and be comfortable, slots in as the most important factor in how often a snake will shed. Adapting their shedding schedule allows snakes to better survive in changing conditions.
