Longest-living spider known to science dies in Australia at age 43

A trapdoor spider named "Number 16" lived for 43 years in southwestern Australia, making her the longest-living spider known to science. She was first documented in 1974 by arachnologist Barbara York Main during a long-term study. Number 16 outlived many of her peers, remaining in the same burrow throughout her life. She surpassed the previous record holder, a Mexican tarantula, who lived to 28 years. Her death in 2016 was likely caused by a parasitic wasp. Trapdoor spiders are known for their unique burrowing behavior and ambush hunting techniques. They construct trapdoors to conceal their burrows and rely on vibrations to detect prey. Their adaptations help them thrive in harsh environments.
