- Dozens of animal species, from ants to whales, have well-documented abilities to detect the geomagnetic field and use it for orientation and navigation.
- After some false starts, researchers may have now located the organs for this magnetic sense, and they are finally understanding the physics that underpins it.
- Some animals may use microscopic magnetic particles to detect magnetic fields; others might harness quantum effects on certain pigments in the eye.
