“ Animals have evolved over billions of years to camouflage
themselves into their surroundings under the kind of light
that we and other predators ordinarily see with. But they
tend to be much warmer than their environment—so, with
thermal imaging, they stand out really brightly against this
cooler background.” —Steven Longmore, Liverpool John Moores University
