Eels are fascinating creatures.
Young eels start their lives on the other side of the world, in the warm waters of the Atlantic Ocean's Sargasso Sea, some 4000 miles across the Atlantic. The eggs hatch into transparent larvae which were once considered to be a separate species to the adult eel. Indeed Aristotle thought eels were born from earthworms. The larvae spend three turbulent years swimming and drifting with the Gulf stream currents, until they reach the coasts of Europe. When they reach British waters they are only 6cm long.
