The Eels Travel Back to the Sagaso Sea

If the eel can't travel back to the sagaso sea, it also never goes through the last metamorphosis. And then it seems like it can live almost forever in that stage. It kind of raises the question of what home is exactly. Is home where you originally came from, or is home where you were living for 50 years, exactly? There's a famous eel in sweden. According to the story, it was a boy that catched the eels in the 18 fifties and put it in the well, and there it stayed.
