Regardless the reasons behind getting a dolphin into captivity, it is important to know that dolphins do not like captivity.

Dolphins are captured by humans mainly for three purposes:

1. Display and entertainment.
2. Research
3. Military

While scientists have been more and more conscious of having dolphins in captivity, there is a large number still on research facilities, however lately scientists make more experiments on wild dolphins.

There are not records for the capture and research by Military because of the secret nature of the experimentation.
