Black wolves do not occur naturally. A 2008 study at Stanford University found that the mutation responsible for black fur occurs only in dogs, so black wolves are the result of gray wolves breeding back with domestic canines. The mutation is a dominant trait, like dark hair in humans, and is passed down to the majority of offspring. It is not entirely clear what benefit black fur has for the animals; they do not seem to be more successful hunters, but do show a marked improvement in immunity to certain infections.

The Utonagan is a breed of dog that resembles a wolf, but in fact is a mix of three breeds of domestic dog: Alaskan Malamute, German Shepherd, and Siberian Husky.

Last weekend three baby Maras were born at Amsterdam’s Artis Royal Zoo. Maras mate for life and usually have one to three babies every year. Newborns are so well developed they can begin to graze within a day.

Maras (Dolichotis patagonum) are the fourth largest rodent in the world, after capybaras, beavers, and porcupines, reaching about 18 inches (45 cm ) tall. In the wild, Maras live in dry, grassy areas in South America. With their long, thin legs and tall ears they seem much like a hare, but the Maras are actually a subfamily of the guinea pig. They can make jumps of 2 meters.
