Field Frame Friday: There is no hiding from me, EYE see you!

Jumping spiders (phylogenetic family: Salticidae) of all arthropods (i.e. invertebrates with an exoskeleton)! In addition to the 2 sets of eyes seen in this photo, jumping spiders also have 2 sets of eyes on the top of their head. Each set has specialized function, from detecting changes in light, motion, and color, to the ability to perceive ultra-violet light (think of how things look when a black-light is on) and depth perception. With these 4 sets of eyes, jumping spiders are able to have a 360-degree view of the world!
