Dolphins are one of the few mammals who have teeth that are undifferentiated. In othe words, the teeth have all the same shape and function. There are no teeth for cutting, biting, crushing or chewing, as the dolphin uses its teeth to grip and to rake (scratch) other dolphins to determine dominance. Here the trainer has the difficult task of feeding three hungry dolphins, each out of its own labeled container. Containers contain a specific diet for each animal and are a means of monitoring the animals' intake to help assess their daily health.
