The study has shown whales experience decompression sickness, a disease that forces nitrogen into gas bubbles in the tissues and is caused by rapid and prolonged surfacing. Although whales were originally thought to be immune to this disease, sonar has been implicated in causing behavioral changes that can lead to decompression sickness. [3]
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."
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 spermaceti organ in sperm whales is shaped like an elongated barrel and sits on top of the whale's melon. Historically, the spermaceti oil found within it was used in a variety of products – including lamp oils, candles, and lubricants – providing the economic basis for the sperm whaling industry. [ 2 ]
Four more sperm whales eventually surfaced. Sperm whales are massive deep-sea predators with a gray body, pointed teeth and a block-like head. Naturaliste Charters shared a video of the rare ...
