Although it might seem the most mundane of fish when pulled from the mud of creeks, ponds, rivers or the sea, the eel's life cycle is one of the most remarkable on the planet. Freshwater eels are born, according to current scientific theory, in remote ocean depths, and journey thousands of miles to fresh water where they spend their lives, before returning to the ocean to mate and die. Richard Schweid chronicles these creatures in all their aspects: their natural history to their market value; their occurence in art and literature; and their present threatened status.
