useful wrinkles

有些動物滿身皺紋,並不是因為牠們老了!以大象為例,牠們只有幾個汗腺,而且不能用來調節體溫,所以透過皺起的皮膚來散熱。生活在狹小隧道裡的裸鼴鼠,鬆弛的皮膚讓牠們能更容易活動。

some animals are so wrinkly, but that’s not because they are old! elephants have only a few sweat glands and couldn’t regulate their body temperature with them. therefore, their wrinkles helps them disperse heat and keep them cool. their wrinkled skip also help traps moisture which make the coolness last longer. naked mole rats is also have useful wrinkles. they live in narrow tunnels and their loose skin could help them move around easier inside their skins!
