Giant Carnivorous Centipedes

Giant Carnivorous Centipedes are, of course, super-creepy. Perhaps you’ve seen footage of one eating a mouse. What I didn’t realize was that they also eat bats:

Centipedes in general are carnivorous, though this term usually refers to a diet of smaller bugs or scavenged remains. The Amazonian giant centipede, however, creeps out at night to stalk even larger victims. Groping through the darkness with its long antennae, the centipede will make a meal out of any number of unsuspecting small animals, including lizards, frogs, birds, and mice. With one quick motion the S. gigantea snags its prey and injects an extremely potent venom. The animal is dead after a very brief, thrashing struggle, allowing the centipede to gorge itself on the catch.

But the natural hunter’s most impressive skill is that which is demonstrated inside the caves of the Amazon jungle. In an environment completely devoid of light, the centipede scurries across the damp floor, stepping over writhing mounds of beetles to scale the wall and clamber across the ceiling into a position near the center. The giant centipede then grips the stone with it rear legs, allowing its forward segments to dangle into the cave below. Its front section sways as its legs wriggle through the air in search of the intended target: a passing bat.

The fast-flying bats have little warning of the centipede’s presence, and within moments one is snatched from the air in mid-flight. The S. gigantea’s toxic venom works quickly as the bat hopelessly attempts to squirm from the grasp of many legs, only to succumb to the poison seconds later. There, dangling from the cave ceiling, the centipede eats every scrap of flesh from its prey over the period of about an hour. It then pulls itself back up to the ceiling and climbs down the wall to return to the dark, damp corner of the cave from whence it came.
