These myriapods — not insects, which have six legs — are not usually lethal to humans, but should still be avoided if possible (via Candide Gardening). Their toxic venom can cause severe pain, swelling, and nausea, and they will bite to defend themselves if they feel threatened. Luckily, these centipedes are nocturnal, so humans rarely come across them; even if they do, they’re slow-moving and avoidable.

The centipedes are already remarkable for their ambitious prey, but how they catch that prey is even more amazing — and slightly terrifying. To catch bats, the Amazonian giant centipedes have been known to crawl into bat caves and climb the walls until they are near or on the cave’s ceiling. Then their front legs will grab hold of the bats, dangling from the cave walls, with only a few of their rear legs holding on for support. They sustain this precarious position, ironically similar to a sleeping bat, for extended periods of time, even while holding and eating their much heavier prey. Perhaps it’s for the best that these critters do their business in the dark.
