非洲象是世界上最大的陆地哺乳动物之一。它们以其巨大的体型和独特的外貌而闻名于世。其中，最引人注目的特征莫过于其宽大的耳朵。那么，为什么非洲象的耳朵会如此特别大呢？
一、适应环境：
- African elephants have large ears because they help regulate their body temperature. The large surface area of the ear allows for efficient heat dissipation.
二、沟通功能：
- The size and shape of the elephant's ears also serve as communication tools. Elephants use these structures to send messages to other members of the herd through infrasound waves.
三、防虫咬：
- Elephant ears can act as natural defences against insect bites. The rough texture of the skin on the outside of the ear provides protection from harmful insects.
四、运动效能：
- The larger surface area of the ear contributes to better balance and stability during movement.
