The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. [3] Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
They are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible differences between the two groups are that porpoises have a less pronounced beak, and have spade-shaped teeth as opposed to conical.
Dolphins and porpoises are kept in captivity. Bottlenose dolphins are the most common, as they are relatively easy to train, have a long lifespan in captivity and have a friendly appearance. Bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine.
The new species was dubbed Tamanend’s bottlenose dolphin, scientific name Tursiops erebennus. Researchers with NOAA and the University of Miami, among others, worked for eight years studying 147 ...
Porpoises are distinguished from dolphins by their flattened, spade-shaped teeth distinct from the conical teeth of dolphins, and lack of a pronounced beak, although some dolphins (e.g. Hector's dolphin) also lack a pronounced beak. Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates.
They found considerable differences and evolutionary divergence, and suggested that the offshore ecotype be retained within T. truncatus while T. erebennus was resurrected as the scientific name for the nearshore type. [3] In the dolphin's original description in 1865, Cope did not provide an explanation for "erebennus" as the species name.
The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is one of three species of bottlenose dolphin in the genus Tursiops.The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it receives in human care in marine parks and dolphinariums, and in movies and television programs.

A 6.5 foot-long bottlenose dolphin was found dead in Port Royal Dec. 5. Dolphins have a cartilaginous flap called a “goose beak,” which keeps the respiratory (trachea) and digestive (esophagus ...
