Summary:
- Researchers have utilized advanced 3D modeling and fluid dynamics simulations to disprove the long-standing hypothesis that the hammerhead shark’s cephalofoil (the hammer-shaped head) evolved primarily to improve maneuverability.
- The study concludes that the unique head shape does not provide a significant hydrodynamic advantage in turning performance, suggesting that the evolutionary pressure driving this trait may be more related to sensory enhancement—such as improved olfaction or electroreception—rather than locomotion.
