New dolphin species discovered
Scientists find that dolphin in Australian waters is a new species
October 2013: A new, fourth, species of a humpback dolphin has been identified in the waters off northern Australia says a team of researchers from the Wildlife Conservation Society and the American Museum of Natural History. Humpback dolphins are named after a peculiar hump found just below the dorsal and live within river deltas, estuaries and coastal waters throughout the Indian, Pacific and eastern Atlantic oceans.
This wide geographic spread has led to the evolution of different species and till now scientists knew of three; the Atlantic humpback dolphin (Sousa teuszii) that lives in the eastern Atlantic off West Africa, the Indo-Pacific humpback dolphin (Sousa plumbea), which ranges from the central to the western Indian Ocean, another species of Indo-Pacific humpback dolphin (Sousa chinensis) that inhabits the eastern Indian and western Pacific Oceans.
“This discovery helps our understanding of the evolutionary history of this group and informs conservation policies to help safeguard each of the species,” said Dr. Martin Mendez, assistant drector of WCS’s Latin America and the Caribbean Program and lead author of the study.
The humpback dolphin grows up to eight feet in length and ranges from dark grey to pink and/or white in colour. The Atlantic humpback is “Vulnerable” according to the IUCN Red List, whereas the Indo-Pacific species is listed as “Near Threatened.” Humpback dolphins are threatened by habitat loss and fishing activity.
“New information about distinct species across the entire range of humpback dolphins will increase the number of recognized species, and provides the needed scientific evidence for management decisions aimed at protecting their unique genetic diversity and associated important habitats,” said Dr. Howard Rosenbaum, Director of WCS’s Ocean Giants Program.
