As early as 1965, marine biologist and bioacoustics researcher William N. Tavolga referred to the fact that sperm whales clicks had been often called "'carpenter' sounds." [1] A later naval technical report in 1980 notes that "sperm whale click trains are called "'carpenter fish' sounds by Navy sonar-men."
[7] [8] [9] Because the calls have also been recorded from blue whale trios from in a putative reproductive context, it has been recently suggested that this call has different functions. [10] The blue whale call recorded off Sri Lanka is a three‐unit phrase. The first unit is a pulsive call ranging 19.8 to 43.5 Hz, lasting 17.9 ± 5.2 s.

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.
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 ...
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 ...
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.
