A newly discovered species of spider has been found working hard to convince its prospective prey in the Amazon that it is already safely dead. The result is a very likeable creature the mushrooms that inspired all these zombies Our last games and spin-off HBO series.
Alexander Bentley, founder of the conservation group Waska Amazonia, first spotted this very goth spider while on a late-night guided tour of a work site in Mera, Ecuador. Bentley trained as a herpetologist in the United States before moving to apply those skills to the study and conservation of reptiles and amphibians in Wasca. On this tour, the researcher just thought he had found a fun, scary example cordyceps: a genus of parasitic fungus that eats the brains of insects such as ants and arachnids such as spiders. (Cordyceps served as the real world inspiration for the zombie apocalypse Our last.)
But to Bentley’s shock, the infected spider—which appeared to be merely a feeding corpse for the fuzzy, yellow, fungal growths that sprouted from it—suddenly began to move. Very immortal.
David Ricardo Diaz-Guevara, a biologist who curates the national arachnid collection for Ecuador’s National Institute of Biological Diversity, he said The New York Times said Bentley’s discovery was “certainly crazy and very surprising.”
The pair eventually identified the new species thanks to a network of enthusiastic volunteers on the citizen-science platform iNaturalist, where Bentley posted pictures of his gruesome find late last summer, not knowing what he had actually discovered that night.
Meet the spider, Taczanowskia waska
Bentley and Díaz-Guevara collaborated with iNaturalist enthusiasts, as well as a third researcher, arachnologist and scientific illustrator Nadine Duperré, to help gather more information about this apparently immortal spider. Dupérré found another specimen of this same species, first collected in Bolivia in 1903, which has since remained unknown, the specimen gathering dust in a German museum.
Although the researchers and their citizen-scientist collaborators found several examples of other spiders mimicking fungi, almost all of them came from fungi. Aranidae a family of orb-weaving spiders. But the Waska site’s new zombie-like spider, orb-like or otherwise, doesn’t spin a web at all. Species named by researchers Taczanowskia waskaplays dead and then plucks its prey in the air with its two front legs.
There are only eight known relatives in the new spider genus Taczanowskaof the approximately 53,000 known arachnid species World spider directory. And, like T. waskathese are all comrades Taczanowska they are patient hunters, literally living away from the element of surprise.
Diaz-Guevara observed a lively Ecuadorian T. waska sample in the lab to better examine hunting behavior and habits for the team’s new study, has been published in Zootaxa last month. Finally, he suspects that the species’ parasitic fungal mask may be as much to evade predators as to deceive them.
“Over time,” he told the New York Times, “(the) spider has evolved to understand that if it imitates something dead, it has a lower chance of being caught.”
More parasitic fungi
After further investigation, iNaturalist users identified this T. waska did not exactly imitate cordyceps but another genus of parasitic fungi of the same family, gen Gibellula. “Gibellula they are almost always located on the underside of the leaf, where they are protected from heavy rain and falling objects,” the researchers wrote in Zootaxa. They added that the newly identified T. waska was “found in exactly the same position.”
The creature’s current known habitat is Waska Amazonia, a 100-hectare (one square kilometer) rainforest bordering the Tigris and Chico rivers in the region Bentley’s conservation team hopes to catalog and protect.
He and his co-authors call their research “a model for citizen engagement in the scientific process” and hope that work like this can inspire local interest in biodiversity. With luck, future research will help make people look like fungus-infected zombies.
