Infrared Sensing in Vampire Bat Foraging
Quick fact
Vampire bats are the only mammals known to detect infrared radiation (heat) to find food. They do this with special heat-sensitive pits on their noses, which help them locate warm-blooded prey and choose the perfect spot to bite.
Why this is interesting
You've probably heard that bats use echolocation to navigate in the dark. But some bats have a secret weapon for finding their next meal—they can literally see heat. How does that work?
