The Mystery of Eels

Eels can be found all over the globe, in fresh and salt water ecosystems alike. But today, risk of over-fishing and the presence of dams and other obstacles that prevent eels from reaching their oceanic spawning grounds pose new threats to an animal that once roamed the planet alongside the dinosaurs. Artist, writer, and naturalist James Prosek explores the mysterious world of the eel.
