The Nanluji dolphin is the only dolphin in the southern hemisphere without a dorsal fin. Distributed around Antarctica. Mainly found in temperate waters, with most records occurring in the northern part of the Antarctic Circle. Often following the Humboldt cold ocean currents to subtropical latitudes, possibly as far as the northern coast of Chile at 19 degrees south latitude. Prey various fish and squid, especially lanternfish, which is the most common. Enjoy group tours, with hundreds or even thousands of people forming groups. Southern ridge dolphins may be mistaken for penguins when they are far away from the sea or traveling rapidly; And when it slowly marches, it will be mistaken for a sea dog or sea lion. The southern humpback dolphin is named after the larger, wingless southern right whale.

Striped dolphin, a species of dolphin in the family of dolphins, with a beak of equal length. Striped dolphins are capable of performing various aerial movements, such as jumping into water and colliding with water. There is a unique behavior of them, called 'tail turning', where they jump high and quickly rotate their tail leaves in front of water. This species was originally very abundant and is a common dolphin in the Pacific Ocean. In recent years, due to the deteriorating ecological environment, the population has sharply declined and urgently needs protection.

Dolphins are mammals of the cetacean family. Due to its round and plump body resembling a pig weighing several hundred pounds, it is named "Dolphin". Dolphins are distributed in the Pacific, Atlantic, and Indian Oceans. [20] They inhabit tropical and temperate waters, are agile in their activities, have strong attachment, and prefer to live in groups with dolphins.
