The most important male funnel-web spider ever recorded — a lethal behemoth measuring 3.6 inches (9.2 centimeters) from foot to foot — has been handed right into a zoo in Australia. The spider is so massive, its fangs might pierce and ship their deadly venom by way of a human fingernail, zoo keepers stated.
Sydney funnel-web spiders (Atrax robustus) are a few of the most venomous spiders on the planet. If untreated, a single chunk can kill a small little one inside quarter-hour and an grownup inside three days.
A member of the general public caught and donated the large arachnid to the Australian Reptile Park in Somersby, New South Wales. The zoo encourages donations to help its spider venom program, which produces life-saving antivenom towards Sydney funnel-web spider and different spider bites.
Emma Teni, the spider keeper on the Australian Reptile Park, named the large spider “Hemsworth” after the Australian actors Luke, Chris and Liam Hemsworth. Earlier than Hemsworth, the file for the largest male funnel-web spider belonged to a 3.1-inch (7.9 cm) arachnid known as Hercules.
“We’re used to having fairly large funnel-web spiders donated to the park, however receiving a male funnel-web this large is like hitting the jackpot,” Teni stated in a press release shared with Dwell Science.

Male funnel-web spiders are sometimes smaller than females, however they’re extra harmful because of a chemical of their venom known as atracotoxin that impacts the nervous system of people and monkeys (it would not have an effect on different mammals). Females lack this chemical, which doubtless explains why males are accountable for all 13 recorded deaths from funnel-web spider bites and a lot of the medically severe chunk circumstances, in accordance with the Australian Museum.
There have been no reported deaths from funnel-web spider bites for the reason that introduction of an antivenom in 1981. The Australian Reptile Park is the one facility in Australia that milks funnel-web spiders for uncooked venom, and the ensuing antivenom saves as much as 300 lives per yr, in accordance with the assertion.
The Australian Reptile Park has designated spider drop-off factors dotted round Sydney, the Central Coast and Newcastle. Workers acquire the spiders and milk them weekly earlier than sending off the venom to a laboratory that makes the antivenom, in accordance with the assertion.
However milking spiders is a tedious course of. “It takes about 150 to 200 milkings to create one vial of antivenom,” Teni stated in a video interview. “We are able to solely milk the male funnel-web spiders, due to the presence of the atracotoxin of their venom.”
Subsequently, Hemsworth is a really welcome addition to the park’s spider inventory. “As a result of Hemsworth is so large, his fangs are large and he produces a lot venom,” Teni stated. When keepers first noticed Hemsworth, “we thought for positive he needed to be a feminine due to his measurement,” she stated, “however upon nearer inspection, he is a boy.”
