There are more than 5000 species of jumping spider. This one, spotted in an Ecuadorian reserve by zoologist Wayne Maddison is both fascinating and terrifying.
One thing that unites all jumping spiders is their four pairs of eyes, with one larger pair set a bit farther back from the others. What's delightfully creepy about this particular arachnid, a member of the sub-family Amycinae, is that its mostly transparent body allows you to see the movements of its underlying visual anatomy.
Want to learn to find your own jumping spiders? Just last week, Maddison uploaded a video guide to arachnid field research. Watch it below, or see the transcript here.
