Part H Is for Hawk, part The Soul of an Octopus, The Book of Eels is both a meditation on the world’s most elusive fish—the eel—and a reflection on the human condition
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 today, in an 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.
Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson crafts a mesmerizing portrait of an unusual, utterly misunderstood, and completely captivating animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea.
Blending memoir and nature writing at its best, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death. The result is a gripping and slippery narrative that will surprise and enchant.

- Both Sigmund Freud (who was one messed up guy) and Rachel Carson (who I knew little about, but who will probably become my next obsession)** were big eel people in their pre-fame careers;Sadly - and pretty much like all such 21st Century natural history/environment stories - this book ends on a discouraging note. Eels - which had already been around for millions of years before humans ever laid eyes on them - are considered seriously endangered, for a variety or reasons: diseases introduced by man (during attempts to breed in captivity - all of course unsuccessful) and then spread through international fish trade (thanks Japanese diners!); dams, locks and hydroelectric turbines which kill up to 70% of all eels trying to swim downstream to the ocean (the essential first step in their reproduction cycle); and of course relentless overfishing (Japan again)…and that's not even looking at the effects of climate change.
- Eels are basically immortal, if prevented from undergoing their final metamorphosis and returning to their original spawning grounds, (just Google "Brantevik eel");
- American and European eels (which differ only in their number of vertebrae) most likely spawn and begin their tremendous Gulf Stream journeys together, before the Americans turn left and the Europeans turn right - and of course, no one knows how or why;
- Eel fishing played a crucial role in both Ireland's "troubles" and the Spanish Basque separatist movements;
- The American eel played a far greater role in the original Thanksgiving than turkeys every did;
- Eels can be prepared in nearly as many ways as Forrest's pal Bubba could prepare shrimp: eel fried with rye straw; eel salted and fried with juniper brush; "sailor's" eel braised in dark beer and butter; eel stuffed with dill and salt; smoked eel; boiled eel; eel soup; etc.;
- And finally, I now know the difference between anadromous and catadromous fish, (the first spend their lives in the sea and then return to fresh water to spawn - think salmon - while the second do the reverse - think eels)
