What is the Longest Living Spider?

Tarantulas, the longest living spider, can live for more than 30 years. That's 10 times longer than a black widow spider and almost 15 times longer than a brown recluse. They do show the signs of aging, however, and many of them go bald on their bodies as they get older.

More facts about spiders:

• The biggest species of spider is the Goliath spider, which can be more than 11 inches (almost 30 cm) in diameter and have a body length of more than 3 inches (9 cm).


• Jumping spiders can solve simple three-dimensional puzzles, and they can learn the behavior patterns of other animals in order to capture them.


• The story that most people swallow four spiders in their sleep during a lifetime has no basis in scientific fact and only a little bit of anecdotal evidence. It is likely, however, that most people are no more than 10 feet (3.05 meters) away from a spider at any time during their lives.

Frequently Asked Questions

What is the longest living spider species?

The title of the longest living spider goes to the female trapdoor spider of the species Gaius villosus, native to Australia. One individual, known as Number 16, was observed in the wild for a period of 43 years, making it the longest recorded lifespan for any spider, according to researchers from Curtin University.

How long do most spider species live?

While the record-holding trapdoor spider lived for over four decades, most spider species have much shorter lifespans. On average, spiders live for about 1-3 years, though this varies widely among species. Some smaller spiders may only live for a few months, whereas larger tarantulas can live up to 20 years in captivity.

Why do female spiders typically live longer than males?

Female spiders often outlive their male counterparts due to a combination of factors. They tend to be larger, which can contribute to their longevity, and they usually remain in one place, reducing the risks associated with constant movement. Males, on the other hand, often venture out to find mates, exposing themselves to predators and other dangers, which can shorten their lifespan.

Can spiders live longer in captivity?

Yes, spiders can live longer in captivity due to the controlled environment that reduces threats like predators, disease, and extreme weather. For example, tarantulas that might live for a decade in the wild can surpass 20 years in captivity with proper care, as reported by arachnid enthusiasts and breeders.

What factors contribute to a spider's lifespan?

A spider's lifespan is influenced by several factors including species, sex, habitat, availability of food, and predation pressures. Genetics also play a role, as does the spider's reproductive strategy; some species die shortly after mating or giving birth, while others may live and continue to reproduce for many years.

How do researchers determine the age of a spider?

Researchers determine the age of a spider through long-term observation in the wild or by raising them from spiderlings in captivity. In the case of the longest living spider, scientists monitored Number 16 over several decades, noting its growth and behavior. Mark-recapture techniques are also used to estimate age and track lifespans in spider populations.
