Every toothed whale except the sperm whale has two sets of phonic lips and is thus capable of making two sounds independently. [29] Once the air has passed the phonic lips it enters the vestibular sac. From there, the air may be recycled back into the lower part of the nasal complex, ready to be used for sound creation again, or passed out ...
The final unit is a long (28.5 ± 1.6 s) tone that sweeps from 108 to 104.7 Hz. [11] The blue whale call recorded off Madagascar, a two‐unit phrase, [12] starts with 5–7 pulses with a center frequency of 35.1 ± 0.7 Hz and duration of 4.4 ± 0.5 s followed by a 35 ± 0 Hz tone lasting 10.9 ± 1.1 s.

[6] [7] The sperm whale uses echolocation and vocalization with source level as loud as 236 decibels (re 1 μPa m) underwater, [8] [9] the loudest of any animal. [10] It has the largest brain on Earth, more than five times heavier than a human's. Sperm whales can live 70 years or more. [11] [12] [13]
Sperm whales, Sharma said, also use a two-level combination of features to form codas, and codas are then sequenced together as the whales communicate. The lower level has similarities to letters ...
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Researchers of chatty creatures like bats, bees, songbirds and whales gather many hours of sound or video recordings and then plug that data into AI language models, the way we might with tools ...
Spermaceti organ within a sperm whale. The spermaceti organ is an organ present in the heads of toothed whales of the superfamily Physeteroidea, in particular the sperm whale. This organ contains a waxy liquid called spermaceti and is involved in the generation of sound. [1]
In whales and dolphins, it is not entirely clear how sound is propagated to the ear, but some studies strongly suggest that sound is channelled to the ear by tissues in the area of the lower jaw. One group of whales, the Odontocetes (toothed whales), use echolocation to determine the position of objects such as prey. The toothed whales are also ...
