magnetoreception

Magnetoreception is the ability of certain animals to sense the Earth's magnetic field. This sense is used for navigation and orientation, particularly during migration. Birds, fish, and even some mammals, like sea turtles, utilize magnetoreception to find their way over long distances. While magnetite, a mineral sensitive to magnetic fields, has been found in some animals, the exact biological mechanisms for magnetoreception are still under investigation. This sense allows animals to orient themselves and return to specific locations, such as nesting grounds or spawning streams.12345
