do humpback whales have dorsal fins

Further, Australian cetologist Graham Ross writes "However, recent morphological studies, somewhat supported equivocally by genetic analyses, indicate that there is a single, variable species for which the name S. chinensis has priority".[6]. In late 2013, researchers from the Wildlife Conservation Society and the American Natural History museum proposed classification of the Indo-Pacific humpback dolphin into three species based on morphological and genetic analysis.

Their flanks are dark gray, and their stomachs are a lighter gray. However, in his widely used systematic account,[5] Rice identified three species, viewing the Indo-Pacific as two species named simply the Indian and Pacific. Orcas, also known as Killer Whales, have dorsal fins. It is listed on Appendix II[10] as it has an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. By the mid-2000s, most authorities[2][3][4] accepted just two species—the Atlantic and the Indo-Pacific. Humpback dolphins are members of the genus Sousa. Who is the longest reigning WWE Champion of all time? The pectoral fins are considerably small and the tail flukes have a well-defined median notch. The dividing line between the two (sub)species is taken to be Sumatra, one of the Indonesian islands; however, intermixing is thought to be inevitable.

The dorsal fin often has a bump (or hump), thus the name of the humpback whale. The pectoral fins are considerably small and the tail flukes have a well-defined median notch. The humpback dolphin's main diet consists of mullet and other fish, though the feeding habits are widely unknown, as this animal is not widely known itself.

is listed on Appendix I[10] and Appendix II[10] of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Humpback dolphins found in Chinese waters are locally known as Chinese white dolphins. [7] Their research indicates that at least four species make up the genus Sousa: the Atlantic humpback dolphin (S. teuszii), two species of Indo-Pacific humpback dolphin (S. plumbea and S. chinesis), and a fourth, new species of Indo-Pacific humpback dolphin found off northern Australia, a distinction with potential to guide conservation efforts for the species. The humpback dolphin has a hump ahead of the dorsal fin, as well as a careen on a ventral side. They have a very long tail that can be up to a third of body length. They have an average size of 52 feet long.

It is listed on Appendix I[10] as this species has been categorized as being in danger of extinction throughout all or a significant proportion of its range and CMS Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them.

See that article for specific issues relating to that subspecies which corresponds to the Pacific humpback dolphin in Rice's classification. Blow.
During the winter, they swim to the warm waters closer to the Equator, around Hawaii, South America and Africa.The exception is the humpbacks that live in the Arabian Sea. Humpback whales have a small dorsal fin located nearly two-thirds of the way down their back, and their backs steeply arch as they dive – this is how the humpback got its name and it helps whale watchers distinguish them from other species. Humpbacks roam all over the world, but exactly where they may be found depends on the time of year.
