The Two-Humps camel is called a Bactrian camel, as he lives in a country which was once called Bactria. That country also has many deserts, like Arabia; but as it is far to the north of Arabia, it is very cold in winter, and the snow then lies very thick on the ground. So try and remember this:
The One-Hump camel lives in a country where there are many miles of desert, and where it is very hot almost the whole year. So the One-Hump camel has to guard himself only from the hot burning sand.
The Two-Humps camel lives in a country where there are also many miles of desert, but where it is very hot in the summer and very cold in the winter. So the Two-Humps camel has to guard himself from the hot burning sand in the summer, and from the cold and snow in the winter.
The Two-Humps camel has in winter a coat of long, shaggy hair on his back to guard him from the cold; and in summer the shaggy hair comes off his back, just as if he were to cast off his thick coat. But the One-Hump camel has only short hair, as the country is too hot all the time to need a thick coat.
