Newborn dolphins are born headfirst, and their mothers help them to the surface to take their first breath. They are unable to swim on their own at first, so their mothers carry them on their backs or fins. Newborn dolphins nurse from their mothers for several months, and they begin to learn to swim and hunt on their own as they grow older.
Dolphins are highly social animals, and they live in pods of up to several hundred individuals. They communicate with each other using a series of clicks, whistles, and body movements. Dolphins are also very intelligent animals, and they have been known to use tools and to solve problems.
Dolphins are found in all of the world's oceans, and they play an important role in the marine ecosystem. They are predators, and they help to control the populations of other fish and animals. Dolphins are also important for the tourism industry, and they are a popular attraction at aquariums and marine parks.
