The species is an average-sized oceanic dolphin. Females weigh up to 150 kg (330 lb) and males 200 kg (440 lb) with males reaching 2.5 m (8.2 ft) and females 2.3 m (7.5 ft) in length. Pacific white-sided dolphins usually tend to be larger than dusky dolphins. Females reach maturity at seven years.
Dolphins are voluntary breathers, who must deliberately surface and open their blowholes to get air. They can store almost twice as much oxygen in proportion to their body weight as a human can: the dolphin can store 36 milliliters (ml) of oxygen per kg of body weight, compared with 20 ml per kg for humans. This is an adaptation to diving. [100]
Males are generally larger and heavier than females. In most parts of the world, adult length is between 2.5 and 3.5 m (8.2 and 11.5 ft); weight ranges between 200 and 500 kg (440 and 1,100 lb). [7] [10] Dolphins have a short and well-defined snout that looks like an old-fashioned gin bottle, which is the source for their common name. [15]
Dolphins range in size from the 1.7-metre-long (5 ft 7 in) and 50-kilogram (110-pound) Maui's dolphin to the 9.5 m (31 ft) and 10-tonne (11-short-ton) orca. Various species of dolphins exhibit sexual dimorphism where the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers.
Its size varies between populations. Dusky dolphins in New Zealand have been recorded with a length of 167–178 cm (5.48–5.84 ft) and a weight of 69–78 kg (152–172 lb) for females and a length of 165–175 cm (5.41–5.74 ft) and a weight of 70–85 kg (154–187 lb) for males. [4]
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.

The key distinguishing feature is the dolphin's coloration—a white to pale-yellow patch is found behind the dorsal fin on both sides of the body. [4] The white-sided dolphin's color variations are unique amongst the standard hues of white, grey, black and blue seen on other pelagic cetaceans. [4]
