Bottlenose Dolphins

(Tursiops truncatus)

Bottlenose dolphins are often seen just offshore in many places in the world as they forage home ranges for food. New research suggests they may travel much farther than we thought. Leaping over or surfing the waves, these dolphins are at home in shallow waters. But that can bring them into contact with humans, or human pollution and debris, and they suffer for it.

The baby bottlenose dolphin has much to learn from his mother about how to survive. He will grow up in a community of dolphins, and as he learns his role in this small society he may establish long lasting relationships with other dolphins about his age.

This captive dolphin looks very fat, but actually he is suffering from a disease. Life in the sea is not easy, and many things can make a cetacean sick. One effect of some forms of human pollution is the suppression of cetaceans' immune systems, making them more susceptible to diseases.
