How long can adult spiders live?

Adult spiders can have varied lifespans depending on the species. While many common household spiders, such as the house spider, generally live for 1 to 3 years, certain species—particularly larger ones—can have significantly longer lifespans. For example, tarantulas are known to live up to 20 years or sometimes even longer in captivity. Thus, the option indicating a lifespan of 1 to 20 years encompasses a broader range that includes those species capable of reaching the upper end of this lifespan spectrum.

Considering the other options, while they suggest various timeframes, they do not fully account for the potential longevity of certain spider species which can indeed live for decades. This highlights the need for understanding the diversity of spiders in terms of their lifespans, especially when considering pet spiders or specific ecological roles in their environments.
