In captivity, trained dolphins will place their head in a swimmer's lab. Trainers must be careful with the animals because dolphins can knock dolphin or injure a person simply by bumping into them hard.
Captive dolphins are usually docile.
But wild dolphins can be very aggressive with each other, and attacking predators. Commons are usually found further offshore, where they somtimes dive 200-500 feet to feed on such species as lanternfish and flashlight fish. They also like anchovy. These bottlenose dolphin swam in front of a camera at Sea World, San Diego. Marine theme parks feature bottlenose more than any other species because they've proven to be highly adaptable to captivity.
