Chapter 1

The Mystery That Slips Through Our Fingers

The European eel has captivated human imagination for millennia, yet remains one of nature's most profound enigmas. Beginning life as transparent larvae in the Sargasso Sea, these creatures drift with ocean currents for up to three years before reaching European shores as glass eels. They then transform into yellow eels, establishing solitary territories in freshwater for decades before metamorphosing one final time into silver eels that journey thousands of miles back to their birthplace to breed and die. This remarkable life cycle stumped even Aristotle, who claimed eels simply sprang from mud. The Book of Eels by Patrik Svensson became an international sensation upon its 2019 release, translated into more than 35 languages and named a Best Book of the Year by numerous publications including The Washington Post and The Sunday Times. Through interweaving scientific inquiry with personal memoir, Svensson creates what The New Yorker called "a highly readable place where science commingles with mythology, neurobiology with poetry, and natural history with human history."

Chapter 2

Nights by the Stream: A Father's Legacy

My father taught me to fish for eels when I was seven. We'd drive at dusk to a stream bordering his childhood home, following a dirt path alongside fields until reaching our fishing spot. Both wearing wellies and vinyl waders-mine yellow, his orange-we'd set ten or twelve spillers along the bank, carefully baiting each hook with worms and following the same ritual each time, including pretending to spit on them for luck. After setting all the spillers, we'd check each one again before heading home in complete darkness. The next morning before dawn, we'd return to check our catch. The experience was largely silent-perhaps because the moonlit stream with its rushing water and flitting bats demanded quiet, or perhaps because memory selectively preserves what fits its narrative. Sometimes we'd find empty lines, sometimes stolen bait. Occasionally, a line would be tangled in reeds with an eel trapped below. And sometimes, we'd feel that distinctive undulating resistance that meant success. I remember catching one that wrapped around my arm with surprising strength as I pulled it from the water, its yellowish-brown body shining in the early morning light. Dad filled a bucket with stream water for our catch, put his hand on my shoulder, and said it was a beauty. These nights by the stream weren't merely about catching fish-they were moments of connection, of passing down knowledge that transcended generations. The eels we caught became focal points for stories about their mysterious lives, tales that sparked wonder in a child's mind. Through these shared experiences, my father wasn't just teaching me to fish; he was showing me how to appreciate the mysteries that nature offers to those patient enough to notice.

Chapter 3

Science's Struggle with the Elusive Eel

The eel forces us to choose what to believe. Aristotle, despite being the founder of systematic zoology and the man who "knew it all," was baffled by eels. In his groundbreaking work Historia Animalium, he meticulously categorized animals based on observation, but when it came to eels, his empirical approach faltered. He claimed they simply spring into being from mud-neither male nor female, laying no eggs nor mating. Throughout history, the eel remained an enigma. Ancient theories abounded: Pliny the Elder claimed eels reproduced by rubbing against rocks, Athenaeus said they secreted life-giving fluid into mud, Egyptians believed they sprang from nothing in the Nile's warm waters. Europeans thought they grew from decomposing vegetation or horse hairs that fell into water. These theories reflect the concept of spontaneous generation-life emerging from lifeless matter. The eel question persisted through centuries. Francesco Redi's 1668 experiments challenged spontaneous generation with "Omne vivum ex ovo" (all life stems from eggs), but even he couldn't find eel reproductive organs. A breakthrough came in 1707 when a surgeon found what appeared to be reproductive organs in an eel from Comacchio, Italy, though scientific debate continued. Finally, in 1777, Carlo Mondini conclusively identified female eel reproductive organs and eggs, proving eels weren't spontaneously generated but leaving many mysteries unsolved. The most famous scientific struggle with eels involved a young Sigmund Freud, who spent a month in Trieste dissecting over four hundred specimens in search of male reproductive organs. His daily routine involved collecting fresh eels from fishermen each morning and spending long hours in his cramped laboratory. Despite his diligence, Freud failed to find a single male eel, concluding his report with scientific caution that neither confirmed nor rejected that the lobed organs he observed were testicles. This early scientific failure proved ironically significant. The man who would later revolutionize thinking about human sexuality couldn't locate an eel's sexual organs. The experience may have influenced his eventual shift from pure natural sciences to psychoanalysis-a field concerned with hidden truths beneath surfaces. Twenty years after Freud's failed efforts, a sexually mature male silver eel was finally discovered off Sicily's coast, revealing that eels simply don't develop visible sex organs until they need them-transforming themselves existentially when the time is right.

Chapter 4

The Dane Who Solved the Eel's Great Mystery

How far must one go to understand an eel-or a person? Johannes Schmidt was just twenty-seven when he boarded the steamship Thor in 1904, beginning what would become a twenty-year quest to find the eel's birthplace. His achievement would later be celebrated in verse by British marine biologist Walter Garstang, who honored "the Danes who solved this age-old mystery." By the early twentieth century, science had made significant progress in understanding the eel. C.G. Petersen had observed the yellow eel's transformation into the silver eel, while Italian researchers Grassi and Calandruccio had identified the willow-leaf shaped Leptocephalus brevirostris as the European eel's larval form. But the central mystery remained: where did silver eels go to breed, and where did all the larvae come from? Schmidt, raised on the grounds of Jgerspris Castle before moving to Copenhagen after his father's death, developed his scientific passion at the Carlsberg brewery's research laboratory under his uncle's guidance. After earning his botany degree and completing his doctoral thesis on mangroves, Schmidt shifted focus to marine animals. In 1903, he married Ingeborg van der Aa Kuhle, daughter of Carlsberg's director, and by spring 1904 was sailing in search of the eel's origin. For seven years, Schmidt trawled European waters from Iceland to Egypt, finding only large leptocephalus larvae measuring 2.5-3.5 inches. Realizing eels must reproduce far from shore, he enlisted Danish shipping companies to help. Between 1911-1914, twenty-three freighters dragged nets across the Atlantic, logging over five hundred catches. In summer 1913, aboard the schooner Margrethe, Schmidt's persistence began yielding results. Moving westward across the Atlantic, he found more numerous but smaller larvae, eventually discovering specimens less than 0.7 inches long. He meticulously measured each transparent willow leaf, recording length, depth, date, and coordinates. Schmidt discovered the larvae of European eels (Anguilla anguilla) and American eels (Anguilla rostrata) commingled in the western Atlantic, distinguished only by vertebrae count. The American larvae grow faster, allowing them to break from ocean currents near American shores after just one year, while European larvae drift for three years before becoming glass eels. Just as Schmidt was closing in on his goal in 1914, the Margrethe sank and World War I erupted. For five years, he analyzed existing data until resuming his search in 1920 aboard the Dana. By 1921, after collecting over six thousand specimens, Schmidt conclusively identified the Sargasso Sea as the eel's breeding ground. Though we now know where eels reproduce, the why remains mysterious.

Chapter 5

Forbidden Waters and Inherited Identities

Sometimes we fished illegally, crossing to the other side of the stream where the fishing rights belonged to the town's fishing club. It was a matter of convenience-their side offered flat meadows stretching to the water's edge, unlike our legal side with its tall grass and steep, muddy banks. The forbidden shore represented something unjust to us-weekend fishermen in expensive gear targeting salmon we'd never even seen alive. One summer, after Dad bought and refurbished an old wooden rowboat, he suggested crossing the stream to set our spillers on the forbidden side. Though I'd never considered this transgression, it suddenly seemed rational-after all, it was the same water. "But if the train comes, we'll have to hide," Dad warned, referring to the railway running along the meadow. We crossed over, reveling in the easier terrain while nervously watching for trains. When one finally thundered past, we extinguished our flashlight and threw ourselves into the grass. I pressed against the ground, desperately trying to disappear, while Dad-I now suspect-was probably just smiling, playing along to make our adventure more exciting. I'd always assumed Dad was passing down a tradition he'd learned in childhood, creating continuity across generations. But my grandfather never fished-he was a teetotaler who never took time off and would have considered eel fishing frivolous. Perhaps Dad fished alone as a boy, but his stories about the stream's abundant past weren't from personal experience. The stories I knew were ones we'd created together, as if nothing existed before us. July and August marked prime eel fishing season, what my father called "eel darkness"-when nights are murkiest and eels boldest. Though he believed this timing was natural, it actually coincided with his summer leave from work, when he could spend nights by the stream instead of sleeping. My father had been a road paver his entire life, rising before six each morning to join his work crew. They labored on commission, paving new roads or repairing old ones in clouds of tar and soot. By late afternoon, he'd return home exhausted, his powerful body shaped by decades of physical labor. The warm asphalt had seemingly seeped into his skin; he perpetually smelled of tar, a mark of the working class. He took pride in his work, occasionally pointing to streets saying "I made that." Yet his identity wasn't tied to being a paver specifically-he called himself simply "a worker," an inherited identity predetermined from birth. Perhaps my inheritance was different: an unspoken understanding that while not all doors were open to me, I remained free to try.

Chapter 6

The People of the Eel: A Vanishing Heritage

Along Sweden's eel coast, about fifty of the original hundred eel sheds remain, dating back to the eighteenth century. Each bears a distinctive name reflecting its history-the Brothers' Shed, the King's Shed, the Smuggler's Shed. While some are abandoned or converted to summer cottages, a few still serve their original purpose for the dwindling brotherhood of eel fishermen. For centuries, eel fishing has defined this region's culture and identity. The fishing rights, called aldratter, date back to at least 1511, when Skane was still Danish territory. When Sweden took control in 1658, the king redistributed these valuable rights to secure loyalty. The traditional eel feast (gille) originated as payment for these fishing rights, with fishermen paying in eels themselves-making the eel a literal currency. What drives someone to become an eel fisherman? Beyond providing income, eel fishing represents a cultural heritage passed through generations. The specialized knowledge-crafting homma traps, flaying eels, reading the sea and weather-isn't learned in classrooms but transmitted through practical experience across centuries. Unlike salmon, eels can't be farmed and won't breed in captivity. The profession often runs in families, with practitioners viewing their work as preserving something greater than mere fishing. Europe's eel fishing communities exist in peculiar places populated by stubborn, proud people who inherit their profession and identity from their fathers. In Spain's Basque Country, glass eels are fished from the River Oria during winter and early spring. The small village of Aguinaga hosts five companies catching these transparent juvenile eels as they return from the Atlantic. Fishermen work cold nights under moonlight, using lanterns to spot the silvery shoals near the surface. The Basques stubbornly maintain this tradition despite dwindling populations. A small portion now costs $60-70 in fine restaurants. Beyond financial incentives, they continue because it's their ancestral right and identity. Like their separatist neighbors, they resist outside authority, determined to fish until the last fisherman-or the last eel-is gone. Around Lough Neagh in Northern Ireland, locals have fished for eels for at least two thousand years. Using spillers-long lines with multiple hooks baited with worms-fishermen work simple boats in harsh conditions, setting 1,600 hooks daily during peak season. Today, these fishing communities face extinction as eel populations decline and calls for protection grow stronger. They argue that banning eel fishing will erase not just livelihoods but cultural heritage, knowledge, and humanity's relationship with the eel itself.

The Uncanny Eel: Between Divine and Demonic

Throughout history, the eel has evoked contradictory feelings-reverence and unease, curiosity and rejection. Ancient Egyptians considered it both a mighty demon and divine being, mummifying eels in tiny sarcophagi alongside bronze gods. The god Atum was depicted with a human head and eel body, symbolizing the union of positive and negative forces. Romans were similarly divided-some refused to eat eels as unclean, while others considered them delicacies. The darker side emerged in accounts from Pliny the Elder and Seneca about the commander Vedius Pollio, who punished slaves by throwing them to hungry eels, later serving the fattened eels to guests. While fish became central Christian symbols-from secret signs between early believers to Jesus making disciples "fishers of men"-eels were excluded from this positive symbolism. In Leviticus, God declares aquatic creatures without fins and scales "detestable," making eels non-kosher in Jewish tradition. This was a misunderstanding, as eels do have both features, though their scales are tiny and covered in slime-showing that when it comes to eels, even divine interpretation falters. In literature, eels often represent the disturbing and macabre. In Fritiof Nilsson Piraten's "Bombi Bitt and Me," the eel appears as a horned monster over ten feet long, wrestling with humans before escaping back to the underworld. In Boris Vian's "The Foam of Days," an eel emerges daily from a kitchen faucet, foreshadowing tragedy when it's finally caught and eaten before the protagonist's love dies from a water lily growing in her chest. The eel embodies what Freud called "unheimlich" (uncanny)-something simultaneously familiar yet strange. Freud's essay on uncanniness may have been influenced by his own frustrating experiences studying eels in Trieste, where the creatures defied his scientific understanding, becoming the perfect symbol of the intellectually unsettling. Yet eels have also been saviors. When the Mayflower Pilgrims faced starvation during their first winter in America, it was Tisquantum (Squanto) who brought them armfuls of eels-"fat & sweet"-which he caught by treading them out with his feet. Though eels saved the Pilgrims and should have become an American symbol, they were gradually erased from the national mythology. By Thanksgiving 1621, the colonists wrote of catching eels "effortlessly" in great quantities, yet the turkey, not the eel, became the feast's emblem.

Chapter 8

The Eel's Consciousness: What Separates Us?

The eel, observed in its natural habitat, presents a modest, unassuming demeanor-eating what's available and staying on the sidelines without demanding attention. Unlike the showy, self-absorbed salmon, the eel seems content without making a spectacle of itself. Though both fish migrate and undergo metamorphoses, their life cycles fundamentally differ: salmon breed in freshwater and live in saltwater (anadromous), while eels do the opposite (catadromous). More significantly, salmon always return to their birthplace to breed, creating genetic differences between populations, while eels from across Europe breed indiscriminately in the Sargasso Sea. Each eel chooses its river seemingly at random, making its journey existentially solitary-perhaps why humans find the eel's secretive nature so relatable. While attributing human characteristics to animals may seem dubious, Rachel Carson did exactly this with the eel. Though financial responsibilities forced her to abandon academic research, she found her path through writing, first creating scripts about marine life for radio, then crafting "The World of Waters"-a piece her supervisor deemed too literary for a government pamphlet but perfect for Atlantic Monthly. This launched her writing career, leading to her 1941 book "Under the Sea-Wind" where she anthropomorphized marine creatures to make them comprehensible. The book follows three animals, including an eel named Anguilla who feels, remembers, and yearns-a creature described as experiencing life almost like a human while maintaining scientific accuracy. What truly separates humans from animals like the eel? Historically, Rene Descartes claimed animals were mere "automata" lacking souls and therefore awareness, while humans possessed both. Carl Linnaeus briefly challenged this distinction in 1758 when he categorized orangutans in the same genus as humans, raising questions about souls and consciousness across species. Eventually, Darwin's theory of evolution eliminated the concept of an unchangeable soul, reducing the perceived gap between humans and animals. Modern science has further narrowed this difference, showing animals can experience pain, fear, grief, and even love. Many criteria once thought to separate humans from animals-awareness, tool use, abstract thinking, language-have proven insufficient or erroneous. Yet philosopher Thomas Nagel argues in his famous 1974 essay that while animals certainly possess consciousness, humans can never truly know what it's like to be another creature. Our human experiences fundamentally limit our ability to comprehend the consciousness of beings like bats or eels, whose sensory perceptions create entirely different states of mind. Eels experience time differently than humans. While our aging follows a predictable chronology, eels can extend or compress their life stages depending on circumstances. A study in Ireland found silver eels ranging from eight to fifty-seven years old-all at the same developmental stage. For eels trapped from completing their journey home, life becomes an endless waiting, teaching us that despite how slowly seconds tick by, life passes in a blink.

Chapter 9

The Long Journey Home: Mysteries That Remain

How does an eel find its way back to the Sargasso Sea? The narrator embraces the mystery, suggesting we should welcome knowledge's limits. While Johannes Schmidt spent eighteen years tracking eels across the Atlantic, our "knowledge" of eel reproduction remains qualified by assumptions. Two essential objections remain: no human has ever witnessed eels mating, and no one has seen mature eels in the Sargasso Sea. This uncertainty acts as both driving force and gravitational pull for eel enthusiasts. Despite extensive research, the eel's migration remains largely mysterious. We know silver eels depart European waters between October and December, with leptocephalus larvae appearing in the Sargasso Sea between February and May. This gives them roughly six months to travel nearly five thousand miles. A 2016 study tracked 700 tagged eels, though only 87 yielded useful data. These eels showed varied behaviors-swimming at depths of 3,000 feet during daylight and rising at night, traveling between 2-31 miles daily, and taking dramatically different routes. Most never completed the journey. Remarkably, European eels from various starting points seem to converge near the Azores before continuing westward together. How do eels navigate back to their birthplace? They possess extraordinary sensory abilities-an olfactory sensitivity comparable to dogs, sensitivity to temperature and salinity changes, and a magnetic sense that detects Earth's magnetic field. Rachel Carson described this as more than mere instinct-a "vague longing" that guides eels who have lived "beyond all reminders of the sea" back to "the large and strange rhythms of a great water which each had known in the beginning of life." Research suggests eels follow the Gulf Stream and North Atlantic Drift in reverse, as though carrying an imprinted memory from their larval journey to Europe decades earlier-a map that persists through all their metamorphoses until it's time to return home. Despite numerous scientific expeditions to the Sargasso Sea, no one has ever seen a mature eel there-alive or dead. Friedrich-Wilhelm Tesch's 1979 expedition found leptocephalus larvae but no eel eggs among thousands collected. James McCleave, conducting eight expeditions since 1981, has detected acoustic signals likely from breeding eels but never caught one. In one desperate attempt, researchers injected 100 female American eels with hormones to induce sexual maturity, hoping to use them as bait in the Sargasso Sea. Most died before departure, and the five survivors mysteriously disappeared with their cages and buoys.

Chapter 10

The Eel's Extinction: A Human Legacy

The eel is dying out at an alarming rate. Though data suggests the population began shrinking as early as the eighteenth century, the decline has accelerated dramatically in recent decades, reaching catastrophic levels. This extinction must be understood within the larger context of humanity's destruction of nature-a phenomenon Rachel Carson first brought to public attention in her groundbreaking 1962 book Silent Spring. While dying from cancer herself, Carson testified before Congress about the devastating effects of pesticides like DDT on all forms of life. Her work led to the banning of DDT in 1972, but her larger warning about humanity's capacity to destroy what it claims to love remains urgently relevant. Throughout Earth's history, five major mass-extinction events have dramatically altered life on our planet. The first, 450 million years ago, killed 60-70% of species through global cooling. The second, 364 million years ago, also caused by cooling, wiped out 70% of species. The third and deadliest, 250 million years ago, eliminated over 95% of all species through dramatic climate change. The fourth, 200 million years ago, saw 75% of species disappear. The fifth and most famous occurred 65 million years ago when a meteor struck the Yucatan Peninsula, contributing to the dinosaurs' extinction along with 75% of all species. Now, many researchers believe we're experiencing the sixth mass-extinction event, happening at unprecedented speed-centuries rather than millions of years. The European eel is critically endangered, facing "an extremely high risk of extinction in the wild." While glass eel arrivals in Europe have plummeted to just 5% of 1970s levels, determining exactly why presents challenges due to the eel's mysterious life cycle. We can't count mature eels at their spawning grounds since no one has found them in the Sargasso Sea. The paradox is painful: to save the mysterious eel, we must solve its remaining mysteries. All known threats stem from human activity. Disease has increased, including the herpes virus anguillae first discovered in Japanese eels and now affecting wild European populations. The parasite Anguillicoloides crassus attacks eels' swim bladders, making their migration impossible. Industrial toxins like PCB cause heart defects and impair their ability to transition between fresh and salt water. Physical barriers like dams and hydroelectric plants kill up to 70% of migrating eels. Climate change alters ocean currents, disrupting both adult migration to spawning grounds and larval return to Europe. The ICES recommendation is clear: human impact on eels should be "as close to zero as possible." If the eel goes extinct, all that will remain are pictures, memories, and stories-a riddle never fully solved. Despite conservation efforts since 2007, including EU fishing restrictions, the eel's recovery has stalled. We remain in what one expert calls a "utopian deadlock" as time passes and populations continue to decline. Is it possible to imagine a world without this creature that has existed for forty million years? The instinctive answer is no, yet all life changes, and just as I couldn't once imagine a world without my grandmother or father, they're both gone now. And the world is still here.

Chapter 11

Final Return: Where Mystery and Memory Meet

I don't remember the last time we went eel fishing, but as time passed, it happened less and less frequently. Not because the eel lost any of its mystery, but perhaps because other mysteries became more important. Our closed little world down by the river found it increasingly difficult to compete with all the other worlds that gradually opened up. This was, of course, a predictable development. People grow up, change, leave, transform, stop fishing for eel. With all the symbolic metamorphoses we go through, some things are inevitably lost. As a teenager, I sometimes took friends to the stream while Dad stayed home. We brought beer and an air gun, shooting at eels and infuriating Dad when he found pellets in the fish. I think he felt we were being disrespectful to both him and the eel. We grew apart naturally-not from conflict but because everything changed. The current that once swept Dad to a new place now carried me away from him. At twenty, I moved to university, a strange place of large buildings and abstract language, where I mimicked exotic social codes and carried books like identity papers. Every summer I'd return home and we'd fish for eel, now using modern bottom fishing with hazel rods, heavy sinkers, and bells that would jingle when we had a bite. We sat in camping chairs through the night, watching bats swerve around our rods, drinking coffee and talking about eels we'd caught and lost. Eventually, my parents bought a small red cabin by a lake. We fished for pike and perch there, exploring the lake's hidden corners, but mysteriously, we never caught a single eel, despite Dad's insistence that "there must be eels here." Dad fell ill in early summer at fifty-six. After months of pain, doctors found an aggressive tumor-the result of years working with asphalt, its warm steam penetrating to his very core. He underwent major surgery and spent months in the hospital, pale and thin, the first time I'd seen him truly weak. It was then my mother revealed that my grandfather wasn't Dad's biological father. Dad's real father was someone unknown who'd abandoned my grandmother when she was pregnant. Dad had spent his first seven years without a father until Nana married the man I called Grandad, who treated Dad as his own son. The surgery gave Dad four more years before the tumors returned, more brutal each time. By sixty, he was too weakened to fight. One evening, I noticed his eyes had turned yellowish-gray, but he avoided my gaze. Weeks later in hospice, I sat holding his stiff, warm hand, listening to his faint, irregular breathing, wondering how one recognizes death. A week after the funeral, we visited the cabin on another warm, stifling summer day. The grass needed mowing, and the osprey soared above the perfectly still lake. Standing by the water with fishing rod in hand, I was called away briefly. Upon returning, I found my rod sliding rapidly through the grass toward the water. I grabbed it just in time, feeling the familiar undulating resistance of a fish that swam toward the water lilies before suddenly turning shoreward. The line became stuck among the rocks by the shoreline. Time stood still as I struggled with the taut line, coaxing and pulling while the rod bent like a reed. Finally sinking to my knees, I peered into the murky water and saw a large, pale gray eel with black button eyes slowly slither up from the shadows. It looked directly at me, as if ensuring I could see it. As I let go of the line, the hook came free and the eel turned back to the hidden depths. I sat there by the water's edge, everything quiet, the sun casting a white sheen across the surface that hid everything beneath like a mirror-a secret that was now mine.
