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 ...
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 ...
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. [11]
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 ...
A sperm whale killed 160 km (100 mi) south of Durban, South Africa, after a 1-hour, 50-minute dive was found with two dogfish (Scymnodon sp.), usually found at the sea floor, in its belly. [71] The sperm whale has the longest intestinal system in the world, [72] exceeding 300 m in larger specimens.
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 ...
Project CETI is an international initiative to understand the acoustic communication of sperm whales using advances in artificial intelligence. [ 1 ] [ 2 ] The project has an interdisciplinary scientific board including marine biologists , artificial intelligence researchers, roboticists, theoretical computer scientists, and linguists.
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
