Be Smart | Why 8 Eyes are Better than 2 | If You're a Spider...

Why do spiders have 8 eyes? It’s a seemingly simple question with a surprisingly complex answer.

We’ll be hanging out with some jumping spiders (the cutest of all spiders) and some jumping spider researchers to investigate how a thumbnail-sized creature with a poppy seed-sized brain ended up evolving some of the most advanced eyes in the animal kingdom, overcoming a few limitations of physics in the process.


We’ll watch as scientists study these spiders in a special eye tracking machine and learn how having 8 eyes instead of two gives these elite predators almost 360˚ vision and almost hawk-level depth perception and resolution.
