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).
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.

Also, fewer than ten pilot whales, Amazon river dolphins, Risso's dolphins, spinner dolphins, or tucuxi are in captivity. Two unusual and very rare hybrid dolphins, known as wolphins , are kept at the Sea Life Park in Hawaii , which is a cross between a bottlenose dolphin and a false killer whale.
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 ...
The Indo-Pacific bottlenose dolphin is generally smaller than the common bottlenose dolphin, has a proportionately longer rostrum, and has spots on its belly and lower sides. [5] [6] It also has more teeth than the common bottlenose dolphin — 23 to 29 teeth on each side of each jaw compared to 21 to 24 for the common bottlenose dolphin. [6]
Hundreds of bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine. [147] The dolphin "smile" makes them popular attractions, as this is a welcoming facial expression in humans; however, the smile is due to a lack of facial muscles and subsequent lack of facial expressions. [148]
Research [9] into the thermal conductivity of the common bottlenose dolphin's blubber reveals its thickness and lipid content vary greatly amongst individuals and across life history categories. Blubber from emaciated dolphins is a poorer insulator than that from nonpregnant adults, which in turn have a higher heat conductivity than blubber ...
Dolphins have been depicted in various cultures worldwide. They occasionally feature in literature and film, as in the Warner Bros film Free Willy. Dolphins are sometimes kept in captivity and trained to perform in shows. The most common species of dolphin in captivity is the bottlenose dolphin, and less than 50 orca were found in oceanariums ...
