Sadly, this behaviour may be one of the reasons that they are targeted in such high numbers in the drive fisheries off the coast of Japan. These dolphins communicate using a series of clicks and whistles, and by using body language such as breaching, jumping, roto tailing and spy hopping. 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. Fish is a firm favourite for these little dolphins and they dine out on the smaller varieties, like lantern-fish, found in mid or deep water. The striped dolphin is among the most studied members of the Delphinidae family and is very abundant in the oceans. Feeding the dolphins has also become a problem, and has led to behavioral changes. This has not been the case in other areas. The causes of these stranding have been changing from epizootic to enzootic. Accessed March 5, 2018. Mediterranean striped dolphins seem to prey primarily on cephalopods (50-100% of stomach contents), while northeastern Atlantic striped dolphins most often prey on fish, frequently cod. This unique coloration distinguishes the striped dolphin from other cetacean species and is the origin of its common name. The unusual mortality events (UMEs) among striped dolphins suggest that parasitic diseases may be increasing in the open ocean due to anthropogenic causes. Striped dolphins are extremely active and fast and spend a lot of time at the surface. A distinctive dark stripe runs from their eye to their tail stock, another from their eye to their flippers.

They may also mix with common dolphins. There are 40 extant species named as dolphins. Two further black stripes run from behind the ear — one is short and ends just above the flipper. Studies have indicated that characteristics of CeMV may be more closely associated with disease in ruminants than carnivore species, which is representative of their evolutionary histories. Striped dolphins are known for their distinct and striking coloration pattern, which includes bold, thin stripes that extend from the eye to the flipper and another set of stripes down the side of the body to the anal region.
