How do dolphins raise their young?

Dolphins are mammals, meaning they nurse their young with milk. So, young dolphins will often stay very close to their mothers while they are fed by their milk. In fact, dolphin calves often stay with their mothers for up to 6 years as they learn necessary survival skills. The maternal instinct in female dolphins can be very prominent, as another dolphin will often help a mother deliver and take care of her baby dolphin for the first few years. On the other hand, fathers are known to eat their own babies in some dolphin species, such as bottlenose dolphins.
