of fishes, squids, and crustaceans such as shrimps. Dolphins use echolocation to navigate and
hunt. Dolphin teeth are designed for grasping (not chewing) food. Bottlenose dolphins have 18 to 26 teeth on each side of the upper and lower jaws, a total of 72 to 104 teeth. A tooth's diameter measures about 1 cm.Dolphin teeth are not replaced when lost.

Their average weight is 150 to 200 kg.On average, full-grown males are slightly longer than females, and considerably heavier.The bottlenose dolphin's streamlined body, together with its flippers, flukes,and dorsal fin, adapt this mammal for life in an aquatic environment.

Babies
Female dolphins are called cows, males are called
bulls and young dolphins are called calves.
Mating season is throughout
the year. Gestation takes 9-17 months
depending on the species. When it is
time to give birth, the female will distance herself from the pod, often going
near the surface of the water. There is
usually one calf; twins are rare. As soon as the
calf is born, the mother must quickly take it to the surface so it can take its
first breath. The calf will nurse from
11 months to 2 years, and stay with its mother until it is between 3 and 8
years old. Calves are about 100 to 135 cm and weigh 10 to 20 kg. Calves
are darker than adults and have several vertical lines on their sides, a result
of fetal folding.
