Sea Turtles Use Earth's Magnetic Field to Navigate with GPS-Like Precision
New research reveals loggerhead turtles learn and remember magnetic signatures to locate key feeding grounds over vast ocean distances.
- Loggerhead sea turtles can learn and retain magnetic field signatures of specific locations, creating a mental map for navigation.
- The study identified two distinct magnetic sensing systems in turtles: one for positional mapping and another for directional orientation.
- Juvenile turtles demonstrated the ability to associate specific magnetic conditions with feeding locations, retaining this memory for months.
- The findings suggest turtles update their magnetic maps throughout their lives, aiding adaptation to changing environments.
- This research provides insights into animal navigation and could have implications for conservation and navigation technology development.
