Size matters: Sharks follow two-thirds scaling law, proving theory
Originally published by James Cook University , at phys.org, on June 18, 2025 Edited by Lisa Lock , reviewed by Robert Egan Credit: James Cook University A new study has used cutting-edge 3D modeling to confirm that sharks follow the "two-thirds scaling law" almost perfectly, with the discovery set to help reshape how we understand biology across the animal kingdom . The study has confirmed that when it comes to body size , sharks play by the rules—and it could reshape how we understand biology across the animal kingdom. For more than a century, scientists have relied on a theory that predicts how an animal's surface area and volume scale with size . Now, researchers from James Cook University (JCU) and the University of Massachusetts have used cutting-edge 3D modeling to confirm this theory in sharks —one of the ocean's...
