Ladies and gentlemen! For your edification and enjoyment, we proudly present [trumpet fanfare] a spider chasing a laser pointer light.
But not just any spider! Nosireebob–this here is a genuine jumping spider. If you look closely, you’ll see she has two rather large eyes, plus a bunch of smaller ones you probably can’t see. That’s what makes jumping spiders unique in spiderdom: they can see! They hunt their prey by sight.
Still, there is one thing that defeats our most concentrated mental efforts–
What does this spider think she sees, when she sees the laser light?
