Brown Huntsman Spider Identified as World's Fastest

Researchers have identified the Brown Huntsman spider as potentially the fastest spider on Earth, based on a comprehensive analysis of over 250 spider species. A team of scientists from the UK and Germany found that this particular species can reach speeds of up to 3.59 meters per second, which translates to approximately 13 kilometers or 8 miles per hour. This significantly surpasses the previously recognized fastest spider, the Moroccan Flic-Flac spider, which moves at a top speed of 1.7 meters per second, primarily by tumbling down slopes. The study involved collecting 162 different spider species from various regions, including London, Germany, North America, Southern Europe, and Australia. Experiments were conducted using special cameras and grooved paper to accurately measure the spiders' running speeds. This research builds upon previous work, including a 2021 study by Dr. Christopher Cleanent from the University of the Sunshine Coast in Australia, who was initially studying spider locomotion rather than speed. Dr. Cleanent noted that spiders utilize a unique hydraulic pressure system, in addition to muscle power, to extend their legs, differentiating their movement from other animals. The Brown Huntsman spider, found along Australia's eastern coast and common in Queensland homes, can grow to be about the size of a human hand. While venomous, their bites are rarely severe. Although the peak speed of 3.59 m/s was momentary, the spider maintained an average speed of about 2 meters per second, which is still remarkably fast. The study also revealed that larger spiders are not necessarily faster, nor are all web-building spiders slow; body weight beyond a certain threshold limits speed due to muscular and mechanical constraints. While the Brown Huntsman is a strong contender, researchers acknowledge that other, faster Huntsman species may exist but have not yet been tested.
