What will happen if we shift the camel from the desert to the polar region ?

Camel is the only domestic animal that can easily survive in desert area. 

But in case, if you shift your camel in the polar region means cold region area, they are not much comfortable to survive in this area as they can survive in desert area.

So here in your mind one question is come, why camel cannot survive in cold area region ?

So first of all you need to know that, all living being on earth is different different living nature and environment, according to their living nature of their body.

Biologically camel not have any type of insulation to prevent body heat from releasing.

But in polar region animals have insulation to prevent body heat from releasing.

So therefore, if we want to shift our camel in polar region, so it is proved very risky for camel heat.
