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).
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
In the Sarasota Dolphin Research Program's library of recordings were 19 female common bottlenose dolphins producing signature whistles both with and without the presence of their dependent calf. [6] In all 19 cases, the mother dolphin inflected the signature whistle when their calf was present, by reaching a higher frequency, or using a wider ...
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).
In general, three different types of sounds are produced by dolphins (and many other toothed whales). These are echolocative click trains, burst pulses and tonal whistles. [38] Dusky dolphins produce all three sounds. [39]: 77 Their echolocation signals are quick and broadband, much like in other whistle-producing species.
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.

The dolphin is a voluntary breather, even during sleep, with the result that veterinary anaesthesia of dolphins would result in asphyxiation. [27] Ridgway reports that EEGs show alternating hemispheric asymmetry in slow waves during sleep, with occasional sleep-like waves from both hemispheres. [28]
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
