Moose Antlers Help With Hearing
Moose are well known for their impressive antlers. But what exactly is the purpose of these huge headpieces? A study in the European Journal of Wildlife Research determined that moose antlers (which can measure up to 6 ft (1.8 m) across) boost the moose's hearing by around 19%. The researchers used a moose skull, antlers, and an artificial ear with a microphone inside to test how the antlers affected incoming sounds. They recorded the highest volume of sounds when the ear was facing sideways, directed at the bowl of the antlers.
