George Karbus Photography/Getty Images(NEW YORK) -- A discovery on how baleen whales are able to sing under water is giving scientists a better understanding on how noise pollution from shipping activity can alter marine mammal's ability to communicate -- and therefore thrive as a species.When the ancient ancestors of whales returned to the ocean from land, they developed major adaptations to make vocal communication feasible under water, according to a study published in Nature on Wednesday.A study into how whales produce their vocals beneath the ocean's surface found that baleen whales -- in...

Earth's largest creatures evolved special parts in their larynx to vocalize their signature songs.

New research into baleen whales shows how they hit such low notes — as well as the limits to how deep in the water they can go to talk to each other. It suggests most of their communication happens closer to the surface, right in the zones of ship noise.

It is one of Earth's most haunting sounds - the "singing" of baleen whales like the humpback, heard over vast distances in the watery realm. Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said on Wednesday. That means baleen whales make their sounds with their larynx, as do humans, while toothed whales - including dolphins, porpoises, killer whales and sperm whales - evolved a different mechanism employing a special organ in their...

Unusual experiments on organs recovered from three carcasses suggest how baleen whales call out at sea.
