Harp Seals
With big round puppy eyes and a soft furry body, baby harp seals are perhaps the cutest newborns on this list. They also may be some of the most greedy. When baby harp seals are born, they are completely dependent on their dedicated seal mamas. The harp seal mother fiercely protects her newborn against potential predators and guards them for the first two weeks of their life in an icy nursery of other moms and pups. During this time, the mom constantly nurses the baby harp seal, while eating nothing, losing about 6 pounds a day. Conversely, during this time, the baby seal feasts on the highly fat-rich milk, and gains about 5 pounds a day. This dedicated mama may not commit the ultimate sacrifice like some of the other moms on this list, but she certainly goes through her own hardships to ensure the health and strength of her young one.
