Fur: Fur is a dense covering of hair that grows on the bodies of mammals. It provides insulation, protection, and camouflage. Fur is typically thicker and more luxurious in cold climates, where it helps animals stay warm. Some common animals that have fur include bears, wolves, foxes, rabbits, and cats.
Hair: Hair is a slender, filamentous protein that grows from the skin of mammals, including humans. It serves various functions, such as insulation, protection, sensation, and communication. Human hair is typically longer and finer than animal fur. However, some animals, like horses and sheep, can also have long hair.
In general, the term "fur" is more commonly used to describe the dense, insulating coat of mammals that live in colder climates, while "hair" is used more broadly to refer to the hair covering on both humans and animals.
