Dolphins use 'echolocation' to navigate. Dolphins emit high-pitched clicks then use the echos that bounce-back from objects in the water to determine the location of those objects.

After the mother breaks the umbilical cord by swiftly swimming away, she immediately returns to her baby and take it to the surface to breathe. The mother nurses the calf with milk until the baby is old enough to eat typical dolphin food, such as fish and squid. The baby dolphin travels by its mother's side for up to three years before making its own way
