Striped dolphins may form mixed species groups with common dolphins (Delphinus delphis). In Japan striped dolphins are the subject of intensive drive hunts, where large groups of dolphins are driven towards the shore and killed for their meat. Agric.Biol.Chem. Striped dolphins, Stenella coeruleoalba (Meyen, 1833), aka blue-white dolphins, range in body lengths from 2.2-2.4m and have a fusiform (tapers at both ends) body, like all dolphins, with tall dorsal fins, long, narrow flippers, and a prominent beak.

Striped dolphin (Stenella coeruleoalba) is one of the most widely distributed dolphins. These are said to give problems to additional food chains as well as doing a full body test to see what hydrocarbons may be passed down through parturition and lactation. Rubio-Guerri C, Melero M, Esperon F, Belliere EN, Arbelo M. Unusual striped dolphin mass mortality episode related to cetacean morbillivirus in the Spanish Mediterranean sea.

This species can be distinguished by the characteristic “brushstroke” of lighter colour to the dorsal fin and the fine lines coming from the eye to the tail. This separates the bluish grey flank from the white ventral surface. (Meyen, 1833) - Striped dolphin Distinctive Characteristics The striped dolphin has the body shape typical of the Stenella and Delphinus species and it is somewhat more robust than spinner and pantropical spotted dolphins, with a falcate dorsal fin and a moderately long beak. The unusual mortality events (UMEs) among striped dolphins suggest that parasitic diseases may be increasing in the open ocean due to anthropogenic causes. Stenella coeruleoalba is a toothed whale and can be recognised as such by the single blowhole and the presence of teeth (rather than baleen). Their bodies are blue with stripes that may be white, cream, or … Caution should be employed when handling these animals due to the possibility of a serious injury if the right steps are not taken in order to ensure both human and animal safety.

Because striped dolphins can move very rapidly to avoid boats, they are often called streakers. They range further into temperate waters than spinner, spotted, or clymene dolphins, and are generally found between latitudes of 50° North and 40° South, although there are some unusual extra-limital records from areas further north. They are named for their characteristic stripe patterns.
