Indri Lemurs Use a Soprano-Like Singing Trick

Indris are lemurs that live in the rainforests of Madagascar. They are the only lemurs known for singing. In a thick forest, trees and leaves can block what an animal can see. So an indri's song helps family groups communicate.
Scientists found something special about these songs. When an indri sings a higher note, it opens its mouth wider. A wider mouth changes the shape of the mouth and throat. This can help the sound travel farther.
Opera singers use a similar idea for high notes. They change the shape of their mouth and throat to make their voices stronger. The indri may use the same kind of trick, even though it is a wild animal in a forest.
