Description

The striped dolphin has a similar size and shape to several other dolphins that inhabit the waters it does (see pantropical spotted dolphin, Atlantic spotted dolphin, Clymene dolphin). However, its colouring is very different and makes it relatively easy to notice at sea. The underside is blue, white, or pink. One or two black bands circle the eyes, and then run across the back, to the flipper. These bands widen to the width of the flipper which are the same size. Two further black stripes run from behind the ear — one is short and ends just above the flipper. The other is longer and thickens along the flanks until it curves down under the belly just prior to the tail stock. Above these stripes, the dolphin's flanks are coloured light blue or grey. All appendages are black, as well. At birth, individuals weigh about 10 kg (22 lb) and are up to a meter (3 feet) long. By adulthood, they have grown to 2.4 m (8 ft) (females) or 2.6 m (8.5 ft) (males) and weigh 150 kg (330 lb) (female) or 160 kg (352 lb) (male). Research suggested sexual maturity was reached at 12 years in Mediterranean females and in the Pacific at between seven and 9 years. Longevity is about 55–60 years. Gestation lasts about 12 months, with a three- or four-year gap between calving. In common with other dolphins in its genus, the striped dolphin moves in large groups — usually up to thousands of individuals in number. Groups may be smaller in the Mediterranean and Atlantic. They may also mix with common dolphins. The striped dolphin is as capable as any dolphin at performing acrobatics — frequently breaching and jumping far above the surface of the water. Sometimes, it approaches boats in the Atlantic and Mediterranean, but this is dramatically less common in other areas, particularly in the Pacific, where it has been heavily exploited in the past. The striped dolphin feeds on small pelagic fish and squid.

Diet

Striped dolphin's diet centers on small pelagic fish and squids. Yet, it also appreciates cephalopods and crustaceans. Generally foraging at night in mid-water, this species has a preference for schooling prey.

Appearance

Striped dolphin is a medium-sized dolphin with a slim, streamlined body. Its skin is smooth and glossy, featuring a striking pattern of light grey or blue on the back, blending into white on its belly. The dolphin's beak is notably long and thin. It has a distinctive, crescent-shaped dorsal fin on its back. There are no significant differences in appearance due to age, gender, or subspecies.

Behavior

Striped dolphin is a highly social and active dolphin species known for its acrobatic displays. This species engages in cooperative hunting strategies, using teamwork to corral schools of fish. Notably, striped dolphin communicates through a range of vocalizations, demonstrating sophisticated social dynamics. It commonly marks territory by creating bubble trails underwater.
