TED-ED: Why do whales sing? - Stephanie Sardelis

Underwater communication is challenging due to poor light and odor transmission, but sound travels faster in water, making it vital for marine mammals. Whales, particularly baleen species, use complex songs for communication. These songs are structured hierarchically and may serve purposes like attracting mates or marking territory. Whale songs are culturally transmitted and evolve over time. Human activities, such as boating and sonar, increase ocean noise, potentially disrupting whale communication. Reducing noise pollution could help preserve these vital communication channels.
