Loggerhead hatchlings navigate using Earth's magnetic map
Loggerhead hatchlings navigate using Earth's magnetic map.
Why it matters
- Reveals how young turtles navigate vast ocean distances.
- Shows they use a magnetic 'map' to locate themselves.
By the numbers
- 8 hatchlings studied.
- 2 months of training to associate magnetic fields with food.
The big picture
- Young turtles' epic migrations rely on magnetic field sensing.
- Combines compass and map senses for precise navigation.
What they're saying
- Users question how shifting magnetic fields affect long-lived turtles.
Caveats
- Turtles may use additional senses for navigation.
- Study focused only on hatchlings, not adults.
What’s next
- Further research needed on adult turtles and other senses.
- Impact of long-term magnetic field changes to explore.
