  Sea lion pups are born with baby teeth, but most of these are replaced with permanent adult teeth by the time the pup is four months old. An adult sea lion has a total of 34 to 36 teeth, with 10 incisors in the front (six in the upper jaw and four in the lower jaw) plus two long canines and 10 to 12 cheek teeth on each side. Sea lions do not chew their food.
