World’s oldest known spider dies in Australia

SYDNEY: The world´s oldest known spider has died at the ripe old age of 43 after being monitored for years during a long-term population study in Australia, researchers said Monday.

The trapdoor matriarch comfortably outlived the previous record holder, a 28-year-old tarantula found in Mexico, according to a study published in the Pacific Conservation Biology Journal. The spider did not die of old age but was killed by a wasp sting, researchers said. Named Number 16, the spider helped scientists to unlock important information about the behaviour of an arachnid that can be found across Australia, including in domestic gardens. “To our knowledge this is the oldest spider ever recorded, and her significant life has allowed us to further investigate the trapdoor spider´s behaviour and population dynamics,” said lead author Leanda Mason from Curtin University. A research project to study trapdoor spiders in the Central Wheatbelt region of Western Australia was first launched in 1974 by Barbara York Main, during which Number 16 was found and monitored.
