ZEBRA CROSSING LIVE QUIZ

Sounds reach one of our ears first and then the other. The time delay in between is too short for us to perceive but it is long enough for the brain to process to determine the source of the sound. This deceptively simple feat is denied to frogs, lizards and birds because the distance between their eyes is too small. Well, then, how do they hear? Elementary. They have an air-filled cavity that connects their two eardrums. These are called “internally coupled ears” or ICE. This “tunnel in the head” is clearly visible when light falls into one ear of a gecko and then shines out of the other ear.
