Dark Roasted Blend posted a fantastic series of spider photos not too long back. If you want to stare jumping spiders in the face, then you must read it (those iridescent orbs are hypnotic).
But what really fascinated me were the species of salticidae (jumping) spiders that look like ants. Don't believe me? Then count the eyes and legs and tell me those aren't spiders. Mimicry at its finest, people. The proverbial wolf in sheep's clothing. Or, the spider in ant's chitin.
