Remarkably little is known about the European eel, Anguilla anguilla. So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even in our age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery.

The European eel, Anguilla anguilla, is one of the strangest creatures nature ever created. Remarkably little is known about the eel, even today. What we do know is that it’s born as a tiny willow-leaf-shaped larva in the Sargasso Sea, travels on the ocean currents toward the coasts of Europe - a journey of about 4,000 miles that takes at least two years. Upon arrival, it transforms itself into a glass eel and then into a yellow eel before it wanders up into fresh water.
