Mexican researchers identify the sounds of the vaquita, the world's most endangered marine mammal.

Every day, Mexican biologists cling to that hope as they fight to save a creature whose life hangs by a thread. The vaquita (Phocoena sinus) is the world's most endangered marine mammal and is at risk of extinction. It lives exclusively in the northern part of the Gulf of California, also known as the Sea of ​​Cortez, located west of Mexico. There, Cárdenas and other researchers monitor the sounds and observations of the species. To summarize, collagen contributes to healthy nails, hair, and skin, and strong bones and joints.
