I am Tabby/Dusky Dolphin,
I am highly gregarious and acrobatic dolphin found in coastal waters in the Southern Hemisphere. I was first identified by John Edward Gray in 1828. I am very closely genetically related to the Pacific White-sided Dolphin, but current scientific consensus is that they are distinct species.Though I and Pacific White-sided Dolphins are traditionally placed in the genus Lagenorhynchus, recent molecular analyses indicate that they are more closely related to the dolphins of the genus Cephalorhynchus. If true, this would mean that these two species must either be transferred to Cephalorhynchus or be given a new genus of their own.My Physical descriptionI am a short to medium in length in comparison with other species in the family. There is significant variation in size among the different population areas. The largest of my species Of Duskies have been encountered off Peru, where they are up to 210 cm in length and 100 kg in weight. The back of the dolphin is dark grey and dorsal fin is distinctively two-toned—the leading edge matches the back in colour, but the trailing edge is a much lighter greyish white.I have a long, light grey patch on their foreside leading to a short, dark grey beak. The throat and belly are white. There are two blazes of white colour running back on the body from the dorsal fin to the tail.I may easily be confused with Peale's Dolphins when observed at sea.My Population and distributionThe population of my species of Dusky Dolphins is unknown, but authorities do not fear for the survival of the species at the moment. The Dusky Dolphin is distributed in coastal waters of Chile, Argentina and the Falkland Islands, Namibia and the west coast of South Africa and all around New Zealand.I may also be resident populations off Tasmania and New South Wales and several small islands in the South Atlantic and Indian Oceans. An aerial survey off Patagonia in the mid-1990s indicated that there was a local population in excess of 7,000 individuals. I can move over great distances (one individual had a confirmed range of 780 nautical miles) (1,440 km). However it is not believed that they follow a migatory pattern.My Conservation and dolphin-watchingOutside Peruvian coastal waters, the main danger to my species Dusky Dolphins from humans is the accidental catching of individuals by fishing trawls. In the mid-1980s around 400–600 animals were killed annually off Patagonia due to individuals becoming trapped in nets. Rates appear to have declined since then, due to tighter regulations on the fishing industry. However, in Peruvian waters, in addition to accidental catches, there is continuing deliberate catching via nets and harpoons. The number of animals killed each year in this area runs into the thousands and is a cause of concern for conservationists.On account of their highly acrobatic displays and movements in large groups called pods, my species of Dusky Dolphins are firm favourites with dolphin-watching enthusiasts. Several boat operators from Kaikoura, on New Zealand South Island are either dedicated to watching me or watch my species in combination with tours aimed at watching Sperm Whales.My Size of adult: 4ft 6in to 5ft 9in
