Bottlenose Dolphins Found worldwide in temperate and tropical waters, usually in coastal areas, but also mid ocean. They are often seen inshore in estuaries, even entering rivers, and an offshore form is found in the open ocean. Offshore bottlenose dolphins are sometimes seen with other dolphin species, and whales. These dolphins have a crooked humped dorsal fin, wide at the base rising to a triangular pointed tip. They grow to up to 3m.
Calves display the same patterns but are lighter in colour.
They have a prominent triangular dorsal fin, pointed flippers, and slender streamlined body. The size of adult females is approximately 2.4m with males being larger at 2.6m.

Several of the Mandurah dolphins have severely disfigured dorsal fins which were no doubt damaged by boat propellers. Dolphin Images Images are displayed in thunbnails.
