  • Bottlenose dolphins (Tursiops truncatus) have a relatively short beak and a high, with a hooked and prominent dorsal fin.

    Bottlenose dolphins are widely distributed throughout the world in cold temperate and tropical seas and generally do not range poleward of 45° in either hemisphere.

    New Zealand is therefore at the southern most point of their range. Limits to the range of this species appear to be temperature related.

    They are found both offshore and in many enclosed areas such as the Mediterranean, Black and Red Seas. Population densities appear to be higher close to shore, where these dolphins tend to travel in groups of about 30 individuals.
