or many years, biologists have puzzled over exactly where they go and what they do after leaving our rivers.
Now scientists using satellite tags have tracked 22 eels, revealing what they do in the first 1,300km of an epic 5,000km migration.
Using this method, biologists hope the whole journey to the Sargasso Sea will soon be revealed.
The results of the tracking study are published in the journal Science.
They provide unique insights into the migratory behaviour of the European eel (Anguilla anguilla), including the direction and depth the eels swim.
"It's exciting data because no-one has managed to do this before," says
Dr David Righton from the Centre for Environment, Fisheries and
Aquaculture Science (CEFAS) in Lowestoft, UK, a member of the
multinational team that undertook the study.
