Bottlenose dolphins live in warm waters and tropical waters throughout the world, including the Pacific Ocean, Baltic Sea and the Atlantic Ocean. There are two types of bottlenose dolphins, inshore and offshore, with varied body forms and color. The inshore bottlenose dolphins are darker in color and larger than offshore ones.
Bottlenose dolphins have a carnivorous diet, mainly eating bottom dwelling fish, squid and shrimp. They stick together in groups of two to 15, while the offshore herds travel with hundreds of other bottlenose dolphins. They use echolocation, making up to 1,000 clicking noises per second to track their prey. Using echolocation, bottlenose dolphins can find out the size, location and shape of the target.
