Many species of birds and marine mammals have advantages due to their unihemispheric slow-wave sleep capability, including, but not limited to, increased ability to evade potential predators and the ability to sleep during migration. Unihemispheric sleep allows visual vigilance of the environment, preservation of movement, and in cetaceans ...
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 ...
Unlike most animals, whales are conscious breathers. All mammals sleep, but whales cannot afford to become unconscious for long because they may drown. They are believed to exhibit unihemispheric slow-wave sleep, in which they sleep with half of the brain while the other half remains active. This behaviour was only documented in toothed whales ...
While knowledge of sleep in wild cetaceans is limited, toothed cetaceans in captivity have been recorded to exhibit unihemispheric slow-wave sleep (USWS), which means they sleep with one side of their brain at a time, so that they may swim, breathe consciously and avoid both predators and social contact during their period of rest.

At the end of the day, it’s all about finding the sleep noise that sounds like music to your ears, says Dr. Maddox: “Every noise evokes different feelings in people, and right now, we don’t ...
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 .
