They are very attached to their mothers. Each dolphin has its own signature song and very original whistle or sound. Gestation of a bottlenose is about twelve months, and a newborn calf is three and a half feet long. Another female helps the mother with the birth, and the calf usually makes its way to the air on its own. But if they are in trouble, they are helped.
Bottlenoses are rare among dolphins in that they have excellent vision both in and out of the water.
Under these definitions, you might think that dolphins are the smartest animals in the kingdom. Dolphins brains are larger than humans', they have adapted perfectly to their environment, and they adjust, communicate, socialize, and have compassion for each other. Their ability to mimic sounds is an ability that dolphins share only with humans. They can be taught to communicate with humans and learn a few sentences of our language. It is a mystery how dolphins make sounds, since they have no vocal cords.
