Longest Living Spider Species
The longest living spider species is the trapdoor spider, with some individuals documented to live over 40 years. Most spiders live only one to two years, making these extended lifespans unusual.
Research published by the Australian Museum confirms that certain trapdoor spiders in Australia can reach ages of 43 years or more. Their slow metabolism and burrowing lifestyle contribute to their longevity.
Why Trapdoor Spiders Live So Long
Trapdoor spiders spend most of their lives in secure silk-lined burrows. This protection reduces predation and exposure to harsh weather. Their low energy needs and steady hunting habits also support a longer lifespan.
Other Long Lived Spider Species
Some tarantula species, especially those from South America, can live 20 to 30 years in captivity. Female tarantulas generally outlive males, which often die soon after reaching maturity.
