The lifespan of snakes can vary significantly depending on the species, environmental factors, and captivity versus wild conditions. While some snakes have relatively short lifespans, others can live for several decades. Here are some examples:

1. Ball Python (Python regius): Can live for 20 to 30 years or more in captivity.
2. Corn Snake (Pantherophis guttatus): can lives past 15 to 20 years in captivity.
3. Burmese Python (Python bivittatus): Can have a lifespans of 20 years or more in captivity.

It’s important to note that these are general estimates, and individual snakes may vary. Additionally, some large snake species, like boas and pythons, have the potential to live longer with proper care and husbandry in captivity. In contrast, smaller species or those living in the wild may have shorter lifespans due to predation, environmental factors, or other challenges they face in their natural habitat.
