A common bottlenose dolphin (Tursiops truncatus). A dolphin is an aquatic mammal in the clade Odontoceti (toothed whale).Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
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.

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).
For humans, flashing a smile is an easy way to avoid misunderstanding. And, according to a new study, bottlenose dolphins may use a similar tactic while playing with each other.
Atlantic white-sided dolphins jump and breach more frequently when in larger groups, as this behaviour might have a social context. [16] They have a wide vocal repertoire which includes squeals, whistles, clicks and buzzes. [17] [20] It is suggested that vocalisation is used for communication as noise production increases during socialising. [20]
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
Southern right whale dolphins are generally gregarious and have been documented in aggregations of more than 1000 individuals [35] although small groups of one to 10 have also been reported. [ 28 ] [ 31 ] [ 35 ] Mean group size estimates differ and range between 52 and 368 off northern Chile, [ 16 ] [ 7 ] [ 36 ] however, they typically live in ...
