Anecdotally, I threw in a cricket as prey for a scorpion in a glass jar I captured at my apartment, thinking the scorpion would eat it. The scorpion was pretty young, and not much larger than a nickel, but I thought it would be sure to kill the cricket, which seemed like easy prey. I forced them to come into close contact, and the scorp stung the cricket, which started jumping around like crazy trying to flee. I came back later that day, and the cricket was dead as a door nail, still in tact. The scorpion, on the other hand, was missing legs, and it's tail and had been separated from the rest of its body. So much for trying to keep a pet scorpion! Lesson learned: crickets are surprisingly tough insects!

Sloths spend nearly all of their life in the tree tops, where they hide from predators. Some of their predators, like jaguar and ocelots, don't hunt in the treetops. The sloth can't effectively defend itself against predators, and some, such as Harpes Eagles, do hunt in the canopy.

Australian lizard
It ducts its head to protect its unprotected face and underside, positions itself to where its tail is facing the foe, and backs itself into it. The quills stick in, and are hard to get out. If the quills get in the mouth, the offender might not be able to eat.
