Eels Consume Their Own Bones to Survive Migration

To survive an arduous swim thousands of miles long without eating anything on the way, European eels apparently lose a significant amount of bone in a way that keeps them alive and moving, a new study finds. This finding could yield insights that will help scientists prevent or reverse human bone loss, the researchers said. In order to spawn, European eels (Anguilla anguilla) undertake a 3,000-mile-long (5,000 kilometers) migration from European freshwaters across the Atlantic Ocean to the Sarga
