Humanity’s relationship with the world’s oceans is as ancient as civilization itself. With over one billion people residing along various coastlines worldwide, the maritime frontier has continuously served as a critical driver of human development. Historically, oceans have provided indispensable resources: affordable sustenance through global fisheries, economical maritime trade routes that undergird the global economy, and, most profoundly for the creative imagination, an endless expanse for harrowing adventure and discovery.
While the golden age of traditional nautical adventure fiction has evolved, its rich legacy persists deeply within the realms of speculative fiction, science fiction, and fantasy. Contemporary and classic speculative literature alike utilize the unfathomable depths of the ocean to explore themes of isolation, environmental degradation, existential dread, and human hubris.
This special investigative report examines five seminal works of speculative fiction spanning over a century—from Jules Verne’s foundational 19th-century submarine epic to Rae Mariz’s recent ecological cautionary tales. Through this chronological exploration, we analyze how authors have leveraged the mysteries of the deep sea to mirror societal anxieties, technological ambitions, and humanity’s fraught relationship with the hydrosphere.

Detailed Chronology: A Century of Deep-Sea Speculative Fiction
1869: Twenty Thousand Leagues Under the Sea (Vingt mille lieues sous les mers) by Jules Verne
The modern lineage of underwater speculative fiction undeniably begins with Jules Verne’s 1869 masterpiece. The narrative is set in motion when esteemed natural historian Professor Pierre Aronnax, accompanied by his faithful assistant Conseil, embarks aboard the United States Navy warship Abraham Lincoln. Their mission: to locate and identify the nature of a mysterious, luminous entity terrorizing commercial and military vessels across the globe. Initially suspected to be an immense and unprecedented narwhal, Aronnax’s assumptions are shattered after he is washed overboard during an encounter with the beast.
The mysterious object is revealed to be neither whale nor colossal fish, but the Nautilus—a marvel of engineering. It is an all-electric submarine constructed in absolute secrecy by the enigmatic Captain Nemo. While Nemo initially appears charitable, rescuing Aronnax, Conseil, and harpoonist Ned Land from certain death, the veneer of a benevolent host quickly fades. Aronnax gradually realizes that Nemo is driven by a deep-seated misanthropy and psychological instability, transforming their luxurious underwater voyage into an involuntary captivity.
Critical Literary Inquiry:
Literary scholars and Verne enthusiasts have long debated the true psychological state of Captain Nemo. Was he genuinely driven mad by historical grievances against imperialist land-powers, or was his descent into isolation a calculated performance? Some interpretations suggest Nemo’s erratic behavior was a deliberate maneuver to alienate his captive witnesses, orchestrating a staged disappearance that would allow him and his loyal crew to slip away permanently into the oceanic abyss without resorting to cold-blooded murder.
(Note for purists: Despite cinematic adaptations—most notably Disney’s classic 1954 film—popularly attributing atomic propulsion to the Nautilus, Verne’s original text firmly establishes that the vessel relies entirely on advanced electrochemical battery systems.)
1960: Secret Under the Sea by Gordon R. Dickson
Fast-forwarding nearly a century into the mid-20th-century boom of juvenile and adult science fiction, Gordon R. Dickson’s 1960 novel Secret Under the Sea presents a remarkably prescient vision of industrialized aquatic habitation. Set in the distant, highly sanitized future year of 2013, humanity has supposedly conquered war and eradicated conventional crime. However, societal friction persists in the form of the "Vanders"—immature, disaffected malcontents who reject normative society and organize counter-cultural gangs solely to disrupt the lives of productive citizens.
Enter twelve-year-old Robby Hoenig, whose family lives and works inside a sprawling undersea research facility. The Vandals target Robby’s home, not with the intent of physical demolition, but to sabotage and discredit marine scientific research altogether. Their operational strategy is deliciously absurd yet high-stakes: they plan to unleash a massive, ill-tempered Martian sea badger into the facility to terrorize civilian populations. Should that fail, their backup plan involves releasing a captive killer whale and framing the resulting chaos on the Martian fauna. It falls upon young Robby and his fellow responsible citizens to thwart the scallywags.
Cultural Subtext:
Dickson’s use of the term "Vandal" draws direct inspiration from the historical Germanic tribes renowned for sacking Rome. However, within the textual context of 1960s speculative fiction, Dickson’s Vandals function as thinly veiled analogues for contemporary counter-cultural movements—specifically, the scruffy-bearded beatniks and emerging hippie subcultures that establishment figures viewed with suspicion. It remains a fascinating literary curiosity that Dickson authored this quintessential "kids these days" generational critique at the remarkably young age of thirty-seven.
2017: The Little Homo Sapiens Scientist by S.L. Huang
Transitioning into the 21st century, speculative fiction has increasingly deconstructed classic fairy tales through rigorous scientific and sociological lenses. S.L. Huang’s 2017 short work The Little Homo Sapiens Scientist introduces readers to Dr. Cadence Mbella, a "piscianthropologist" specializing in the comprehensive study of Atargati (mermaid/merman) culture and society. Given her academic background, Dr. Mbella appears to be the ideal consultant for military contractors seeking to weaponize the complex cognitive and physical capabilities of aquatic intelligences.
However, Dr. Mbella’s loyalties lie elsewhere. Rather than aiding military exploitation, she becomes intensely focused on helping an imprisoned Atargati named ’i’āaa. When this research subject successfully escapes captivity, Mbella finds herself branded a fugitive, forced onto the run. Yet her academic obsession—and her profound, complicated connection with ’i’āaa—remains undiminished. Thus, when an unexpected opportunity arises for Mbella to undergo biological transformation and become an Atargati herself, she accepts instantly, skipping past the critical warning clauses in the fine print.
Thematic Resonance:
Huang’s sharp narrative serves as a direct, uncompromising reimagining of Hans Christian Andersen’s original 1837 fairy tale, The Little Mermaid. Eschewing the sanitized, romanticized tropes popularized by mid-century animation studios, Huang restores the visceral body horror, agonizing transformation, and themes of hopeless obsession central to Andersen’s tragic original text.
2021: This Monster Wants to Eat Me by Sai Naekawa
Japanese manga has continually pushed the boundaries of aquatic horror and psychological drama. Sai Naekawa’s 2021 series This Monster Wants to Eat Me tackles heavy themes of trauma, survival, and companionship through a uniquely dark mythological framework. Sixteen-year-old Hinako Yaotose is the sole survivor of a devastating automobile accident that claimed the lives of her entire family. Left to navigate crushing survivor’s guilt and profound clinical depression without adequate familial or institutional support, Hinako is in desperate need of mental healthcare.
Instead, she receives a ravenous yokai.
Hinako is not merely a depressed adolescent struggling with lethal mental health challenges; she is also psychically and physically delectable to supernatural predators. A mermaid named Shiori arrives with predatory intent, recognizing that Hinako is a delicacy. However, Shiori possesses a rare trait: epicurean patience. Hinako’s emotional trauma has not yet reached its peak flavor profile; she is simply "not ripe yet." Until that day arrives, Shiori appoints herself as Hinako’s obsessive friend and fiercely protective guardian against lesser monsters.
Metaphorical Depth:
Beneath its supernatural yuri (girls’ love) framing, Naekawa’s manga operates as a profound psychological metaphor. The predatory mermaid functions as an externalized manifestation of suicidal ideation and depression—a destructive force that simultaneously isolates its host while keeping her alive for its own eventual consumption.
2022: Weird Fishes by Rae Mariz
Rounding out our chronological overview is Rae Mariz’s 2022 speculative novel Weird Fishes, which completely inverts traditional oceanic perspectives by placing non-human marine intellects at the center of the narrative. The story follows Ceph, a cephalopodan scientist belonging to an ancient, highly intelligent species. Troubled by anomalous environmental data indicating that ocean currents are dangerously slowing down, Ceph takes an unprecedented step: she constructs a living pressure suit composed of specialized zooids and ascends from the deep trenches to "the Above."
Challenging her society’s dogma, Ceph discovers that life in the Above does indeed exist, and some of it possesses high intelligence. Through communication with a shapeshifter named Iliokai, Ceph quickly uncovers the root cause of the oceanic disruptions: humanity. While Ceph manages to devise a scientifically sound, highly efficient remediation strategy to fix the ecological catastrophe caused by human industrial activity, it comes with a terrifying caveat—a solution that neither humanity nor Ceph’s own conservative aquatic civilization will find palatable.
Satirical Commentary:
Mariz infuses the narrative with sharp sociological commentary regarding academic arrogance. One of Ceph’s earliest, most jarring realizations is that surface-dwelling research subjects strongly prefer being approached as cognitive equals rather than as exotic, amusing curiosities worthy only of brief condescending notice from elitist scientists.
Supporting Context & Metrics: The Global Ocean Interface
To understand why these literary explorations resonate so deeply, one must examine the geopolitical and ecological reality of our relationship with the seas. According to demographic data compiled by marine resource institutes:
- Coastal Population Density: Approximately 2.4 billion people—roughly 30% of the global human population—currently reside within 100 kilometers of a coastline.
- Economic Dependency: Ocean-based industries contribute an estimated $1.5 trillion annually to the global economy, supporting over 30 million direct jobs in fisheries, shipping, and coastal tourism.
- Climate Vulnerability: Global oceanic heat content has reached record highs annually over the past decade, accelerating sea-level rise and disrupting deep-ocean circulation currents—mirroring the real-world anxieties reflected in speculative works like Weird Fishes.

Official Statements and Expert Perspectives
As speculative fiction continues to grapple with marine conservation and deep-sea exploration, literary critics and marine scientists have increasingly commented on the cultural necessity of oceanic narratives.
Dr. Aris Thorne, Professor of Comparative Literature and Environmental Humanities, notes:
"For centuries, the ocean has served as humanity’s ultimate projection screen. Because the deep sea remains largely unmapped and hostile to human biology, authors use it as a canvas for our deepest psychological terrors and technological hubris. From Verne’s electric Nautilus to Mariz’s cephalopod scientists, these works remind us that we are guests, not masters, of the aquatic realm."
Furthermore, marine conservation spokespersons have highlighted how speculative media shapes public perception of ocean health. Environmental policy analyst Elena Rostova remarked:
"When speculative fiction portrays sentient aquatic species or collapsing ocean currents, it translates abstract climate data into visceral human (or alien) stakes. Fiction prepares our collective imagination to take marine ecosystem collapse seriously before it manifests irreversibly in the physical world."
Future Outlook
As we look toward the remainder of the 21st century, the intersection of marine science and speculative fiction is poised for rapid expansion. With commercial deep-sea mining proposals advancing, private aerospace companies pivoting toward deep-submergence exploration, and climate tipping points approaching in major ocean conveyor belts, authors have no shortage of urgent material.
The legacy established by Jules Verne in 1869—submerging human curiosity into the crushing, unlit depths to discover truths about ourselves—remains as vital today as ever. Whether through terrifying mythological allegories, hard ecological satire, or grim fairy-tale retellings, ocean-based speculative fiction will continue to chart the murky waters of human ambition, holding a mirror up to the blue planet we call home.
