Whose work first showed that fish can navigate using Earth’s magnetic field?
Quick Answer
The classic evidence is associated with Franz and Eleanor Persaud and later researchers such as Kenneth Lohmann and Cathy Lohmann. Their experiments in the late 20th century helped demonstrate magnetic orientation in sea turtles and fish.
The Full Story
Research by Kenneth Lohmann and colleagues was crucial in showing that some marine animals can detect Earth’s magnetic field and use it for navigation. In studies from the 1980s onward, fish and other sea creatures were tested in controlled settings that altered magnetic cues. The results showed that magnetic information can guide movement, especially during long-distance migration. This work helped open a major field in animal navigation biology.
