Howling wolves.

The wolf (Canis lupus) is a mammal of the order Carnivora. It is sometimes called timber wolf or grey wolf.

It is the ancestor of the domestic dog. A recent study found that the domestic dog is descended from wolves tamed less than 16,300 years ago south of the Yangtze River in China.^[2]

There are many different wolf subspecies, such as the Arctic wolf. Some subspecies are listed on the endangered species list, but overall, Canis lupus is IUCN graded as 'least concern'.
