How do jumping spiders see so well compared with other spiders?
Quick Answer
Jumping spiders have unusually sharp vision for spiders, with large forward-facing eyes that help them judge distance. They use that vision to stalk and leap accurately onto prey.
The Full Story
Jumping spiders are famous for their advanced eyesight, especially the pair of large principal eyes at the front of the head. These eyes provide good resolution and depth perception, while the smaller eyes help detect motion and monitor the surroundings. This visual system supports active hunting instead of web-building. Many species use visual displays in courtship and can even recognize shapes and movement patterns at close range.
