The extraordinary reason why scientists are collecting #seaturtle tears
Researchers are hoping they may unlock one of animal biology’s greatest mysteries.
Researchers know sea #turtles, like many other species, navigate using Earth’s #magnetic field. However, how animals sense magnetic forces is unknown. The theory scientists are exploring is that sea turtles might also have magnetotactic bacteria — living compasses — in their bodies, and somehow be able to read them.
