Length and Weight at birth: At birth, individuals weigh about 22 lb (10 kg) and are up to 3 feet (1 m) long.

Length of pregnancy: 12 months

Range:  This is a widely-distributed species, found in tropical and warm-temperate waters of the Atlantic, Pacific, and Indian oceans, as well as many adjacent seas, including the Mediterranean.

Likelihood of being seen on a whale watch in Massachusetts coastal waters:  Highly unlikely

Preferred food: The main diet of striped dolphins consist of fish, squid, krill, cephalopods, crustaceans and octopus.

Unusual characteristics: The striped dolphin is the only species that takes part in roto-tailing. This is the process of leaping very high out of the water and rapidly rotating the tail while in midair.

Appearance: With the classic dolphin shape, the striped dolphin’s most remarkable feature is the distinctive pattern of blue and white stripes along the body. It is mainly blue with a white to light grey stripe following the spine. The sides are darker than the belly. The beak is fairly long and prominent, the dorsal fin is tall, and the flippers are long and narrow with black stripes

General Information: The colors often depend on the habitat so that they can blend in well with their surroundings. The stripes and colored patterns become more evident as the Striped Dolphin gets older.

Unusual Habits:  They sometimes leap more than 20 ft. (6m) above the surface of the water when playing or swimming.

Status: The listing with the IUCN for the Striped Dolphin is low risk, but it is classified as conservation dependent. This means that without a conservation plan of action in place, they will move into the classification of being threatened or endangered within the next 5 years.

Threats:  Hunting/whaling; entanglement from fishing nets
