Not as in sissies, but as in born big. The biggest babies on earth, easily, and at birth already rank amongst the largest full-grown animals. They pop out at around 8,800 pounds with a length of some 26 feet. They gain 200 pounds a day! Their growth rate is likely one of the fastest in the animal world, with a several billion-fold increase in tissue in the 18 months from conception to weaning.
