Freshwater eels are almost infinitely improbable creatures. They
spawn and die in the middle of the ocean, often associated with
undersea mountains. Their tra- parent, leaf-like larvae move with
ocean currents for months or years until they approach the mouths
of freshwater rivers. Then they undergo a dramatic transf- mation
in morphology, physiology and behavior. They move from their
planktonic oceanic environment, migrate upstream and live for
several years as apex fre- water predators. Then, almost
impossibly, as they become sexually mature, they reverse their
migration downstream to the ocean and back to spawning grounds to
complete their life cycle. The dramatic changes in their life
cycles are incredible. The efforts to unravel the details of their
life history have been truly daunting. Much of the past research
was the work of dedicated individuals who devoted their lifetime
research to these fishes. Freshwater eels merit a separate chapter
in almost any textbook dealing with ichthyology, marine biology or
animal migration. We know a great deal about some aspects of the
biology of freshwater eels. However, our understanding of their bi-
ogy still resembles a work of art as much as a work of science. To
some it appears like the sweeping brush strokes of a Japanese Zen
landscape, to others it resembles the work of a French
impressionist, and to still others it appears as magic realism.
