Why are camels not afraid of sandstorms?

The distant ancestors of camels crossed the Bering Strait from North America and migrated to Asia and Africa 654.38+0 billion years ago. Through continuous evolution, some physiological structures and functions that can adapt to the desert climate have gradually emerged.

In order to resist frequent sandstorms in the desert, camels have thick hair in their ears, which can prevent sandstorms from entering their ears; There are double eyelids and thick long eyelashes, which can prevent sand from entering the eyes; The nose wing can be opened and closed freely, which can prevent sand from entering the nostrils.

In addition, camels rarely open their mouths in the desert, on the one hand, to retain water, on the other hand, to keep out the wind and sand.

Camel has a hump (whether it is one or two), and its hump can keep water well, which can keep it from looking for water for 7 days.

Camel's feet are also very distinctive. It can walk on the hot sand and is not afraid of being burned. ?

A camel can tell the weather, that is, it can know when a sandstorm is coming, and it can squat down to avoid it.
