Harp Seal Pups
These pups tend to compete for their mother’s milk and attention. To do this, they’ll vocalize and push each other out of the way to establish dominance within the group. But the saddest part about these pups’ existence is that the harp seal mother abandons its pup after just 12 days. Because the mother does not eat during that time, it must go and search for food and leave the pup to fend and survive all by itself. They abandoned the pup on ice, and after about 8 weeks, if it survives, it’s then old enough to get into the water to swim and look for food (Mental Floss).
