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 ...
Sea turtles and dolphins can be found in the bay, while cattle, white-tailed deer, nilgai and bobcats can sometimes be seen near the shore. [10] In Laguna Madre, Bird Island Basin is home to a wide variety of birds when wet, including black-necked stilts, roseate spoonbills, great egrets, American white ibis, and many others. [17]
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).
Researchers with NOAA and the University of Miami, among others, worked for eight years studying 147 skulls and 43 spines of stranded bottlenose dolphins. Some specimens were found in South ...

Globicephalinae is a subfamily of oceanic dolphins that includes the pilot whales (Globicephala spp.), the pygmy killer whale (Feresa attenuata), the rough-toothed dolphin (Steno bredanensis), the false killer whale (Pseudorca crassidens), the melon-headed whale (Peponocephala electra), Risso's dolphin (Grampus griseus), and the snubfin dolphins (Orcaella spp.).
The newly resurfaced footage, originally captured in March 2016, shows an Amazon river dolphin, also known as botos, urinating into the air in Brazil’s Tocantins River.
Despite being found in geographic locations similar to those of 'true' river dolphins such as the boto, the tucuxi is not closely related to them genetically. Instead, it is classed in the oceanic dolphin family (Delphinidae). Physically, the species resembles the bottlenose dolphins, but differs sufficiently to be placed in a separate genus ...
