The Sea Otter’s Fur

 

The fur of the sea otter is denser than that of any other mammal, with some one million hairs per square inch (155,000 per sq cm).

海獭世界上皮密度哺乳动物,每平方厘米皮肤155000根毛。

When the otter swims, its coat traps a layer of air close to its body. That air acts as an insulator, preventing the cold water from coming into direct contact with the animal’s skin and sapping its body heat.

海獭游泳时,它皮毛可以大量空气,在皮肤表面形成保温层。有这个保温层,海獭身体直接接触冰冷海水,从而避免热量流失。

What do you think? Did the heat-insulating fur of the sea otter evolve? Or was it designed?

认为怎样?海獭高效保温皮毛,是进化的,还是经过设计呢?
