Awesome Adaptation--Howler Hyoid Bone
While the official title is debatable the accolade of "World's Loudest Animal" just may go to the Howler Monkey of Central and South America--can be heard three miles away in dense jungle. Imagine yelling to a friend from that far away--can't even do that across a parking lot! Here's how and here's what will blow your ever-loving mind. What an awesome adaptation! Take your time admiring how the hyoid bone has been modified and engorged in the Howler.
