Australian scientists discovered what they believe is the oldest spider in the world, a creature that probably survived the previous record holder by about 15 years.
In a study published in the journal Pacific Conservation Biology and cited by Phys.org a team of researchers led by the Ph.D. student at Curtin University Leanda Mason analyzed a spider female trap Giaus Villosus who had recently died during a separate population study. It is believed that the spider, which received the name "Number 16", died at the age of 43, making it 15 years older than a 28-year-old tarantula from Mexico that was once considered the oldest spider in the world. .  According to the Telegraph the study of the spider population is the "work of life" of the Australian biologist Barbara York Main, who had first encountered the Number 16 in 1974, not long after he was born. The team from Curtin University continued where Main had been and was able to obtain more information about the creature that could be the oldest spider in the world, including details about its life history, its age and its cause of death.
"We know that this is the oldest spider ever recorded and its important life has allowed us to investigate further the behavior of the trap spider and the popular dynamics," Mason said in a statement.

Mason credited Main's previous investigation, claiming that the trap spider can live like this throughout life due to its " characteristics of the life cycle ". "Like his sedentary lifestyle, low metabolism rate and the fact that he lives in" unspoiled native bushland "where he does not run the risk of being attacked by predators.
" We are really miserable about it, "Mason added, referring to to the dea of what his team believes is the oldest spider in the world.
According to the Telegraph trap spiders are a poisonous species, with the males of the species generally more visible to humans , because of their tendency to leave home in search of a partner, females, on the other hand, rarely move more than a few meters away from their burrows. Animal Corner also notes that trap spiders may have a length of 2.5 to 4 centimeters and come with eight eyes, a robust frame and eight thick and short legs, although these creatures are often popular as exotic pets, the publication warned that the species is aggressive by nature and should only be kept by experienced exotic pet owners.
Considering how the female trapdoor spider tracked by Main since the 1970s became the oldest known spider through its unusual behavioral traits, the associate professor at Curtin University and co-author of the study, Grant Wardell- Johnson said that his team's research should be decisive in determining how climate change and deforestation could have an effect on the species.
