Giant 'flying' Joro spiders love big cities. A new study found their ability to chill out in stressful situations may be why

The saga of the large invasive Joro spiders that parachute through the air isn't over. A new study found that the critters with 4-inch-long legs are truly built differently, with hearts that are able to withstand the loud and bustling noises of big cities.
University of Georgia researcher Andy Davis made the discovery while conducting cardiac stress tests on Joro spiders and their cousin, the golden silk spider. The research, published in Physiological Entomology on Monday, found that the species know how to chill out and stay calm when put in heart rate-raising situations.
The Joro spider, also known as Trichonephila clavata, "is known for making webs not only in natural green spaces but also in cities and towns, often on buildings and human dwellings," the study says. "The stress reactions of Trichonephila spiders could be characterized as 'even-tempered,' which may factor into their ability to live in habitats with frequent disturbances."
