Dolphins

Dolphins are interesting because they display almost behavior at times. For example, they display the human emotions of joy and sadness. During training, when they do something correctly, they squeal excitedly and race toward their trainer. When they make a mistake, however, they droop noticeably and mope around their pool. Furthermore, they help each other when they are in trouble. It one is sick, it sends out a message, and others in the area swim to help it. They push it to the surface of the water so that it can breathe. They stay with it for days or weeks-until it recovers or dies. They have also helped trapped or lost whales navigate their way safely out to the open sea. They are so intelligent and helpful, in fact, that the U.S. Navy is training them to become underwater bomb disposal experts.
