Cattle are found all over the world, from as far north as Canada and Russia to the dry inland of Australia. The only continent they are not found on is Antarctica. Different types and breeds of cattle are suited to different environments. "Bos indicus" cattle such as the Brahman breed are suited to subtropical and tropical areas, whereas "Bos taurus" cattle such as Angus cattle are more suited to temperate or colder climates. Their large wide hooves are good in both wet areas and dry grassland. Their hairy coat grows much longer in the winter and has an extra fluffy layer to hold in warmth. They shed this extra layer in springtime in preparation for the hot summer ahead. Most cattle, except those of the "Bos indicus" subspecies do not have sweat glands in their skin, but their wet nose is a useful cooling system. They can also pant like a dog as well.
