     Dolphins are mammals, not fish. They are warm blooded like man, and give birth to one baby, called a
calf, at a time. At birth, a bottlenose dolphin calf is about 90-130 cms long and will grow to approximately
4 metres, living up to 40 years.
     They are highly sociable animals, living in groups, called pods, which are fairly fluid, with dolphins from
other pods interacting with each other from time to time.
      Dolphins carry their young inside their womb for about 12 months. The baby is born tail first, and its
mother will feed the calf for up to 2 years.
      However, the calf will stay with its mother for between 3-6 years, during which time it will learn all
about feeding techniques, social interaction and group hunting.
