Common bottle nose dolphin (Tursiops truncatus) are part of the Delphinidae family and are probably the most well known and recognised dolphin. Recent studies in that the Tursiops genus contains two distinct species the Common bottle nose dolphin (Tursiops truncatus) and the Indo -pacific bottle nose dolphin (Tursiops aduncus).
Additional, research shows that a third species the Burrunan dolphin (Tursiops australis) exists, which inhabit warm and temperate waters.Bottle nose dolphins often live in groups of 10-30 members typically these groups are called pods, however, observations of 1000 plus pods have occurred.
The bottle nosed dolphin feeds on fish which the dolphins forage for, often working in teams to heard the fish into a bait ball. However, dolphins will hunt as individuals, hunting is achieved by initially searching for prey using an echolocation system (natural sonar) by emitting a clicking sounds and listen for the return echo to determine the location and shape so as to decide if the prey is suitable.
Research has shown that bottle nose dolphins also use sound for communication, including squeaks and whistles emitted from their blow holes, in addition to the sounds made when leaping or splashing their tails.
