Scientists find out why whales sing loudly and have unique voice boxes.

Whales have a unique way of singing in the ocean, and scientists have been trying to figure out how they do it. They found that whales have a special kind of voice box that's different from other animals.

Researchers studied the voice boxes of three dead whales and used air to see how they might make sounds. They also made computer models to understand how whales sing in the wild.

Whales evolved from land animals and changed their voice boxes over millions of years to make sounds underwater. Unlike other mammals, whales use a special tissue in their voice boxes to sing.

Experts believe this study is important for understanding how whales communicate. However, they think more research is needed, especially since whales make very diverse sounds.

Noise from ships makes it hard for whales to communicate properly. There's concern that this could affect how whales find mates and survive.
