Vampire Science: How Bloodsuckers Aim Their Bites "Scientists have found the heat-sensing mechanism used by vampire bats to detect their next meal, according to a report in the journal Nature.

The bats – utilizing what are essentially infrared sensors – can then pinpoint the highest concentration of blood closest to their prey’s skin so they can feed more efficiently.

'Vampire bats feed on blood, and it's useful for them to have an infrared detector to be able to find the circulation,' said David Julius, PhD, the Morris Herzstein Chair in Molecular Biology & Medicine at the University of California, San Francisco, who led the research."
