Platypus fur looks plain brown in daylight, but in 2020 researchers discovered it glows blue-green under ultraviolet light. The find came by accident, when scientists shined a UV lamp on museum specimens out of curiosity.
When hunting underwater, platypuses shut their eyes, ears and nostrils. Their bills contain about 40,000 sensors that detect faint electric fields from prey muscles. They locate food in visual darkness with a sense almost no other mammal possesses.
