This story is not for the faint of heart so you’ve been warned.

If you’ve ever wondered how a Chinese red-headed centipede kills its prey, you’re in luck.

Scientists in China have figured out how the centipede kills its victims. The Ssm Spooky Toxin in the insect’s venom affect’s the prey’s brain, which essentially tells its heart to stop.

According to the scientists, “the toxin works by blocking potassium from moving in and out of cells. This blocking prevents the brain from sending signals to the heart to beat, and the animal dies very quickly. … Potassium movement is also important for maintaining many animals’ breathing systems, which means the victim of a bite often starts having problems with their airways.”

If you can stomach it, the video above shows how quickly and effectively this venom works on a mouse.

Sweet dreams…
