Long-haired or "Angora" Hamsters
See also: Syrian hamster variations"Angora" hamsters are commonly known as "teddy bear" hamsters. Females have short, velvety fur in many different colors. Male teddy bear hamsters usually have much longer fur than the female variety, culminating in a "skirt" of longer fur around their backsides.
"Black Bears" are a recent off-shoot of teddy bear hamsters (mutation discovered in 1985), the major difference being their black-colored fur. It can be argued that black bears are just black teddy bears rather than their own breed; on the other hand, black bears were originally selectively bred for their larger size and more docile nature, as well as their color. However, in current stock, this is no longer the case.
