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 average life span of common bottlenose dolphins is at least 40 years old and up to 60 years old, with females typically living longer than males. [37] but in captivity they have been known to live to up to 51 years old. [40] The main threats to bottlenose dolphins depends on their geographic range.
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.
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 melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
Coralling is a method where dolphins chase fish into shallow water to catch them more easily. [63] Orcas and bottlenose dolphins have also been known to drive their prey onto a beach to feed on it, a behaviour known as beach or strand feeding. [64] [65] The shape of the snout may correlate with tooth number and thus feeding mechanisms.
The diet of Atlantic white-sided dolphins mainly consists of herring, hake and squid. [4] However, as opportunistic carnivores, they consume a large variety of prey, including smaller mackerel and various bottom-dwelling fish. [4] They have been observed cooperatively hunting at the surface. [4]
