Arctic Foxes hold an interesting record. They have the largest litters of any wild mammal in the world. While the average is 11 puppies, litters with 22 puppies have been recorded in Russia. Talk about sibling rivalry! Thankfully, they have a father to keep them from fighting. The male Arctic fox is considered one of the most attentive parents of all the canids, a family of mammals that includes wolves, coyotes, and jackals.
