The Australian snubfin dolphin is unusual among recently described mammals in that a population is accessible for scientific study. Nonetheless, the existence of snubfin dolphins in the waters of northern Australia had only become known to western scientists in 1948, when a skull was collected at Melville Bay (Gove Peninsula, Northern Territory).
The snubfin dolphins (Orcaella) contain two of the 35 species of oceanic dolphins that make up the Cetacean family of Delphinidae. [5] The phylogenetic status of Orcaella has long been confused. Although the snubfin dolphins share similar external features with the Monodontidae (narwhal), [ 2 ] a genetic study conducted by Arnason and ...
A total of 65 Irrawaddy dolphins has been found dead along the coast of Trat Province in the past three years. [68] The local fishing industry is blamed for the deaths of the dolphins. [69] In January 2013, over a dozen dead Irrawaddy dolphins were found on the coast of Thailand. These dolphins were said to be dead because of a lack of oxygen.

Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea.Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae (round-headed whales, which include the false killer whale and pilot whale).
It is positioned at the crossroads of the Indian Ocean, the Pacific Ocean, and the South China Sea. [4] The region, characterized by extensive coastlines and numerous islands, is a global biodiversity hotspot with significant marine resources, including a large proportion of the world's reefs and mangroves.
