P. Prominens is a sociable species that is native to Japan and Korea. Up to 300 individual spiders may join together to produce a whole neighborhood of webs, with up to 300 individuals in each web. Zhang’s team noticed that sex always ended with a catapulting male while researching P. prominens’ sexual behavior, according to Shichang Zhang and colleagues at Hubei University in Wuhan, China. The movement was so quick, however, that standard cameras could not capture the specifics, according to Zhang of Hubei University in Wuhan, China.

High-definition video of mating partners recorded the male arachnids’ speed from around 32 cm/s to 88 cm/s, according to researchers. That’s equal to about 909 meters per hour to just over 1 mile per hour.
