Namibian desert Hotrod ants have evolved to tiptoe around to avoid baking to death in the unrelenting sun. But other dangers lurk, like these terrifying real-life sarlacc pits created by antlions.
As with the baby iguana versus snakes, BBC Earth has done a wonderful job of making viewers experience the terror. If the antlion can't catch the ant, it starts throwing sand at it to pull it back into the pit. Nightmare fuel!
