 Songs of great whales

                Baleen whales emit a series of very high frequency and very low range sounds that are beyond the hearing range of humans. These sounds vary significantly depending on the characters of each animal. Although humans cannot hear these low-frequency sounds, because these sounds travel long distances in seawater, the whale song in question carries hundreds of kilometers in the deep sea. These sounds fall within the range of human hearing as grunts, grunts, grunts, and sighs lasting 10 minutes or more. Whales use these sounds to recognize each other, communicate with strangers, attract sex, signal threats, and navigate.

The blue whale can emit a loud sound with a deep voice that can spread over great distances. A few special songs have been identified here. These are the only species spread between animal groups and their clutches. A four-note song like this has been repeatedly heard and recorded by blue whales in Sri Lanka. The song is always the same and consists of three short notes and a long note with a frequency of 110HZ. This lasts for 28 seconds.

Bride whales sometimes emit short (0.4 second) sharp low-frequency sounds that humans hear as a low whine. Minke whales also produce a large number of short waves, grunts, and small sounds with frequencies ranging from 60Hz to 12kHz.
