When they sleep, foxes only do so for 15 – 25 seconds at a time, waking up and looking around before going back to sleep. Dolphins and whales use this method to work out an object’s distance, direction, speed, density and size. ‘Flying foxes use their excellent eyesight more than echolocation, or bouncing sounds, to locate their food at night.’ ‘This structure may help focus the sound emitted by these animals in echolocation and feeding.’ Echolocating sounds are so loud that the ears of dolphins and whales are shielded to protect them.
