2000. & SIMMONDS, M. (Eds) Greenpeace Mediterranean Sea Project p.33-37, CALZADA, N. & AGUILAR, A. It is very common in the western region, extending from the Gibraltar Strait to the Italian Peninsula and Sicily. Striped dolphin - Stenella coeruleoalba Striped dolphins are recognizable by their striking markings, making them one of the most beautiful small cetaceans. The flanks are a light gray color, the flippers are black, and the belly is white. Experimentation of photo-identification technique on striped dolphin (Stenella coeruleoalba, Meyen 1833) in Ligurian Sea. What do striped dolphins look like? There are appreciable differences in reproduction and life history between the Mediterranean population of striped dolphins and the populations of the rest of the world. The Hawaiian stock is thought to number 20,000 individuals but is poorly known in Hawaiian waters. Cetacean distribution related with depth and slope in the Mediterranean waters of southern Spain. 121:65-78, WAFO, E., RISOUL, V., SCHEMBRI, T., LAGADEC, V., DHERMAIN, F., MAMA C. & PORTUGAL, H. 2012. 1993. Other threats: Factors such as climate change could influence the distribution of the species, making its conservation more difficult. The belly is whitish or light colored, while the dorsal part is dark grey. Individual identification characteristics: The striped dolphin (Stenella coeruleoalba) is a cetacean of the family delphinidae, that belongs to the suborder of the odontoceti or toothed whales. Striped Dolphin. One stripe runs to the flipper and the other dips down to the belly. 64:2535-2541, http://www.iucnredlist.org/details/20731/0, http://www.iucnredlist.org/details/16674437/0. This stripe may be absent in some individuals. More importantly than the origin we need to understand the actual scientific classifications of each dolphin. Molecular Ecology 16:2922-2933, GÓMEZ-CAMPOS, E., BORRELL, A., CARDONA, L., FORCADA, J. The pectoral fins are long and slim. The Striped Dolphin is a small sleek compact dolphin with a striking body pattern that gives it its name. Marine Biology 150:149-160, JEFFERSON, T. A., WEBBER, M. A. In: Proceedings of the Mediterranean striped dolphin mortality international workshop, 1991, 4-5 Nov., Palma de Mallorca. 49:2053-2073, CAWARDINE, M. 2004. Another big concern is that the population increased its numbers after the epizootic outbreaks just at the same moment that its available habitat is decreasing, due to human activity. Striped dolphins may occasionally face threats from attacks by natural predators such as killer whales and sharks. Physical maturity comes a bit later, between 13 and 18 years old in males and between 15 and 20 years old in females. On the other side, the Alboran Sea, although the high productivity is explained by the inflow of nutrient rich Atlantic waters through the Gibraltar Strait. Although this criterion does not allow a complete distinction between two individuals, it may be used as a first selection in order to classify the animals in different groups in photo-ID studies. Examinations of stomach contents suggest that the diet of the striped dolphin of the Mediterranean would be mainly composed by different squid species of the families Ommastrephidae, Histioteuthidae, Enoploteuthidae or Onychoteuthidae and different fish species of the families Gadidae, Sparidae and Gonostomatidae. The Striped Dolphin is a small sleek compact dolphin with a long well defined beak, prominent dorsal fin and short tapering flippers. There is another dark stripe that starts at the eye and widens to the pectoral fins. Dorsal fin shape and scars: The size, shape and scars of the dorsal fin (above all those on the posterior margin) are unique for each dolphin and they allow the individual identification of the striped dolphins. The total length of a reproductive cycle is around 3 years. Scars and marks: During their lifetime, cetaceans may get marks and scars due to interactions with other individuals of the same or of other species. & PERRIN, W. F. 1999. The head contains the melon, a round organ used for echolocation. Since then, there has been seen a trend towards the increase of group mean size. Due to the oceanic nature of the striped dolphin, more Marine Protected Areas should be created in Spanish or French waters, in order to ensure the conservation of the species. After lactation, females experience a resting period of 2 to 6 months till the next mating period. The Hawaiian stock is thought to number 20,000 individuals but is poorly known in Hawaiian waters. Dietary plasticity of the oceanic striped dolphin, Stenella coeruleoalba, in the neritic waters of the Bay of Biscay. The striped dolphin is one of five species traditionally included in the genus Stenella; however, recent genetic work by LeDuc et al. On one side, the Liguro-Provençal basin, which thanks to the upwelling of deep waters, is rich in nutrients and zooplankton, and is one of the most productive areas in the Mediterranean Sea. The low density may be explained by the absence of oceanographic processes that would favor primary production. In: G. Notarbartolo di Sciara (Ed. It is the striking body pattern that gives it its name. These marks, above all the ones located on the most dorsal parts, are a good way to identify individuals of striped dolphins in the Mediterranean Sea in photo-ID studies.
