Like most toothed whales, narwhals use sound to navigate and hunt for food. They primarily vocalise through clicks, whistles and knocks, created by air movement between chambers near the blowhole . [ 65 ] [ 66 ] The frequency of these sounds ranges from 0.3 to 125 hertz , while those used for echolocation typically fall between 19 and 48 hertz.
They do not have a true dorsal fin, but do have a narrow ridge running along the back, which is much more pronounced in the narwhal. They are highly vocal animals, communicating with a wide range of sounds. Like other whales, they also use echolocation to navigate. [2]
It has also been proven that whales are extremely social creatures. The noises that are made throughout the entire year (the main sounds being whistles, clicks, and pulsed calls) are used to communicate with other members of their pod.

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 .
Some species, such as the humpback whale, communicate using melodic sounds, known as whale song. These sounds may be extremely loud, depending on the species. Humpback whales only have been heard making clicks, while toothed whales use sonar that may generate up to 20,000 watts of sound (+73 dBm or +43 dBw) [55] and be heard for many miles.

Feeding in the winter accounts for a much larger portion of narwhal energy intake than in the summer: needs a rephrase: feeding accounts for all of a narwhal's energy intake, but it sounds like what we're saying is that they eat more in the winter and then rely on that stored energy through the summer.
When the vocal cords come apart, the voice sounds breathy. At any time, the voice can go from a soft, breathy whisper to a strained hoarse sound, shaking or even breaking, as certain sounds are ...
