Tell me what other animals' ears look like and what they do.

1. Bats have round ears, which are very big compared with their bodies. When a bat flies, its ears are like two horns, which can receive the ultrasonic waves from its mouth, and the hairs on its ears can also detect the slight vibration, which is more severe than the tentacles of a snail.

The dog's ears are pricked up. As long as there is a little noise, it can hear, turn its head and hear voices coming from all directions. On the contrary, pigs' ears are big and drooping, so they are dull and like to sleep.

Mole's ear has no auricle, so it's easy to get around in the hole.

4, big-eared fox, ears account for a large part of the body's driving force. When the weather is hot and short of water, the ear becomes an excellent radiator, which can not only block the invasion of hot sun and heat wave, but also form a small fan-shaped radiation arc on the back and upper part of the big ear. Even in hot noon, the highest radiation surface temperature near the ear will not exceed 13℃. They rely on strange ears to radiate heat accumulated in their bodies.

5. The umbrella-shaped edge of jellyfish has a receiving ball like an "ear". When the storm warning occurs, it will produce infrasound, which can be heard by jellyfish through this receiving ball.

6. A tuft of hair on the tip of a lynx's ear can help it judge which direction the sound comes from. If you cut off that tuft of hair, it will be difficult for it to tell the direction of the sound.
