How do whales sing, and why do they make such complex sounds?

Many whales, especially baleen whales, produce long, low-frequency vocalizations that can travel far through water. They generate these sounds using specialized structures in their larynx and respiratory tract rather than vocal cords like humans use. Some species, such as humpback whales, make elaborate song patterns that can change over time. These sounds help whales stay in contact, find mates, and possibly navigate their environment.
