Here are some exciting info about animal ears and their sense of hearing! Animals often have an incredibly good hearing, but not all of them use their ears to hear. There are even animals that don’t have ears but can still hear.
7. African Elephant
Category: Air conditioning
The African elephant has the biggest ears. But why? Maybe so their trunks don’t look as big? Just kidding! But they must use them to hear, right? Not quite. Their ears are like giant fans. When the sun burns its skulls and the air starts to shimmer in the heat, the elephant pumps blood into its ears. It then flaps them around and the cooled blood flows back into its body. It’s like holding your wrist under cold water. African forest elephants and Asian elephants have considerably smaller ears, as they live under tropical forest canopies.
6. Fennec Fox

The fennec fox is a desert fox. It might only be 15.7 inch (40 cm) tall, but its ears are 15 cm long! They can hear almost anything, even a beetle crawling over the sand. The fennec also uses its ears like the elephant does - to cool down.

The brown long-eared bat has the biggest ears in comparison to its body size. The bat bat hears tones that people can’t hear at all. The animal only grows to 1.9 inch (5 cm) in length but has 1.5 inch (4 cm) long ears. This would be like a human having 55.1 inch (140 cm) long ears. Maybe Little Red Riding Hood saw a bat when she said “What big ears you have!”.
Category: 3D ears
Owls have unusual hearing equipment. You can hardly see them, but the barn owl has one ear that’s higher than the other. On purpose! Active at night, these silent flying owls can pretty much hear in 3D. One ear hears upwards, the other downwards.
