The lifespan of spiders varies greatly depending on the species. Some species of spiders have very short lifespans, lasting only a few months, while others can live for several years. There are even a few exceptional cases where certain spider species have been known to live for over 20 years in captivity.

In general, most spiders have relatively short lifespans. Many common house spiders, for example, live for about one to two years. However, factors such as environmental conditions, availability of food, and predation can influence the lifespan of spiders.

Female spiders tend to live longer than males; male spiders often die shortly after mating or are even cannibalized by the female.

Lifespans mentioned here are general estimates, and there is considerable variation among different spider species.
