Scientists who designed a marine robot to survey ocean life were inspired by eel larvae.

In laboratory experiments that simulated oceanic conditions, the fish responded to magnetic fields, a sensory input that may aid migration.

A mysterious migration is coming to light after more than a century of study.

Researchers are using high-tech solutions to bring the lifecycle of the European eel into sharper focus.
