How Are They Biting? High Speed Video Reveals Unexpected Jaw Movements in Reef Fish

Andy Fell — May 05, 2025 - 5:20pm

Some reef fish have the unexpected ability to move their jaws from side to side, biologists at the ɫ��ɫ have discovered. This ability – which is rare among vertebrate animals – allows these fish to feed rapidly and efficiently on algae growing on rocks. The work is published May 5 in Proceedings of the National Academy of Sciences.

The park, known as the “Galapagos of North America,” protects more than 57,000 square miles around the Revillagigedo Archipelago, a UNESCO World Heritage site composed of a string of four volcanic islands about 300 miles southwest of the Baja Peninsula.
