Scientists discovered male spiders of the species Philoponella prominens can survive encounters with aggressive females because of a unique ability to catapult away.

April 25, 2022, 4:27 PM UTCAcross the animal world there are examples of creatures who use extremely quick speeds to capture prey — or avoid being captured.

This type of spider is also unusual because it lives in groups of up to 300 individuals. They live together in a mass of linked webs, while maintaining their own individual webs within this complex. The males that do spring away often return to the scene to try again. Some males end up catapulting several times after their 30-second trysts.

Further examination with cameras revealed catapulting is possible because the male spider folds its first pair of forelegs against the body of the female spider, and the rapid subsequent extension allows it to spring away.
