Some people are scared of snakes and will panic if they spot one in their backyard, while others see them as a popular pet to keep in the home. But, whether you keep snakes as a pet or are just interested in snakes, you may be wondering, how long do snakes live?

This guide covers the average life cycle of snakes, what factors affect their lifespan, and the lifespan of different snake species. A snake can live as short as two years or as long as 18 years, depending on its conditions and their specie. Let’s take a closer look.

Snake Life Cycle

Snakes start from soft eggs but soon grow into an adult, eating prey of different sizes depending on their own size. Their life cycle is versatile because it depends on the snake species, so there is no fixed time to say how long it takes a snake to become an adult.

Egg

Female snakes can lay between 5 to 20 eggs in every breeding season, and the time for this season depends on the species and the weather conditions.

It’s important to note that some snakes can give birth to live babies rather than laying them as eggs.

The female snake will protect her eggs after laying them until they hatch at the end of the season. The snake species will determine how long they remain eggs before hatching, from weeks to months. During this time, predators eat many eggs since the snakes can’t do anything to protect themselves.

Juvenile snake

The juvenile snake is the young snake that has hatched from its egg.

The little snake simply wriggles out of the eggshell using its body and breaks it with its teeth. A snake’s eggshell is soft and grows as the snake incubates. Immediately a snake comes out, they move around without assistance and can even eat life prey immediately.

Juvenile snakes shed their skin more than adult snakes will.

They will feed themselves and shed their skin many times and remain in this part of the cycle for between a year to five years.

Adult snake

When a snake reaches sexual maturity, it is considered an adult. This can be when they are between 18 months and four years of age, depending mainly on the snake species and how much care it receives as a pet or in the wild. Some adult snakes can live for over a decade, especially those in captivity. For instance, there is a ball python snake that lived up to 60 years Trusted Source www.bbc.com and was still laying eggs.
