This appears at first glance to be a fairly unremarkable red ant- but count the legs! This, amazingly, is an ant mimic spider. Entomologists believe that this mimicry evolved both for hunting and for avoiding predators such as the spider wasp.
Some studies from today (and last week)! An ant, ant-mimic, and some spiders (mouse and long-horned orb spider respectively). Eye-placement on the mouse spiders is inconsistent because the photos I had were… unclear on where the eyes were, so I drew them where I thought they were based on reflections and shadows.
