1. Species Matters
-
Small Snakes (e.g., garter snakes, corn snakes):
Typically live 5 to 10 years in the wild; up to 15–20 years in captivity. -
Medium to Large Snakes (e.g., king snakes, rat snakes, ball pythons):
Can live 10 to 20+ years, often longer in captivity. -
Large Constrictors (e.g., boa constrictors, Burmese pythons):
Average lifespan of 20–30 years, with some individuals living even longer. -
Venomous Snakes (e.g., cobras, vipers, rattlesnakes):
Wild lifespan is often 10–15 years; some live longer in captivity.
2. Wild vs. Captivity
-
In the Wild:
Snakes face predators, disease, accidents, and food shortages. Lifespans are generally shorter. -
In Captivity:
With controlled environments, regular feeding, and no predators, many snakes live much longer — sometimes twice as long as their wild counterparts.
3. Examples
-
Ball Python: Up to 30+ years in captivity (record is over 40 years!)
-
Corn Snake: Around 6–8 years in the wild, but up to 20 years in captivity.
-
King Cobra: Typically 20 years in the wild.
