The water moves against gravity by capillary action. North American horned lizard Getty images This quirky creature has special powers that allows it to wield superiority over potential predators.

But their real super-power is their ability to shoot blood – loaded with foul toxins gleaned from a diet of venomous ants – from their eyes, to a distance of up to nine times their body length.
