Platypuses find food using their electric bills
The platypus is a truly bizarre creature. Not only are these
Australian critters weird to look at with their duck-like bills and beaverlike tails (so odd, in fact, that the scientists who discovered them thought they were being tricked with an elaborate hoax), they’re also some of the only mammals to lay eggs. This ability puts them into the monotreme family along with their cousins, the echidnas. But one of the platypus’ strangest quirks isn’t so obvious.
For years, researchers were befuddled as to how the semiaquatic creatures find their food underwater, particularly considering the fact that they close their eyes, ears and nostrils while swimming. By analysing the creature’s bill they realised that the platypus’ signature accessory isn’t just for show – the digging beak contains over 40,000 electrical receptors, which are used to detect the tiniest movements of prey and locate living creatures with remarkable accuracy.
