Russian fisherman Roman Fedortsov has captured the internet’s attention with his latest deep-sea discovery – a creature so bizarre it seems pulled from science fiction rather than Earth’s oceans. In February 2025, this seasoned sailor shared images of an otherworldly marine specimen that left his 600,000 Instagram followers both fascinated and terrified by what lurks in the ocean depths.
The nightmarish deep-sea creature that shocked social media
Roman Fedortsov isn’t your average fisherman. While many anglers share photos of their prized catches, Fedortsov has built a substantial following by showcasing the strangest and most unsettling creatures hauled from the deep. His Instagram account serves as a gallery of marine oddities that challenge our perception of underwater life.
In early February, Fedortsov posted images of his most disturbing find yet – a slimy, bloated fish with a gaping mouth that bears an uncanny resemblance to the iconic xenomorphs from the “Alien” film franchise. Some followers also noted similarities to extraterrestrials from “Mars Attacks” or the animated character “Megamind.”

The creature’s appearance triggered immediate reactions from viewers, with comments ranging from shock to humor. “That’s 100% an alien,” wrote one follower, while another joked, “That’s my face when I wake up.” Some reactions were more dramatic: “Kill it, burn it, and never catch anything like that again!”
This particular specimen represents the fascinating biodiversity found in deep ocean environments, which can be as mysterious as outer space. Just as our planet harbors numerous active volcanoes beneath its surface, our oceans conceal countless strange life forms adapted to extreme conditions.
Identifying the mysterious ocean dweller
Despite its alien appearance, this creature has been identified as Aptocyclus ventricosus, commonly known as the Pacific spiny lumpsucker or smooth lumpfish. This deep-sea fish belongs to the Cyclopteridae family and primarily inhabits the North Pacific Ocean, particularly in waters near Japan, Russia, and Alaska.
Fedortsov explained that the fish’s bloated appearance resulted from pressure changes as it was brought up from the depths. When deep-sea creatures are rapidly raised to the surface, they experience dramatic changes in pressure that can alter their appearance significantly – often causing internal gases to expand and distort their bodies.
The Pacific lumpsucker has evolved specialized adaptations for life in deep waters. Its most distinctive feature is a suction cup on its underside, formed from modified pelvic fins, which allows it to attach to rocks and other surfaces in strong currents. This remarkable adaptation demonstrates how marine life evolves unique solutions to environmental challenges.
Marine biologists continue to study these unusual species to better understand ocean ecosystems. The dedication of scientists to understanding aquatic environments recalls other remarkable interactions between humans and nature, such as when an orangutan reached out to help an ecologist it thought was in danger, showing that extraordinary encounters happen throughout the natural world.
The passion behind unusual marine discoveries
Roman Fedortsov’s dedication to documenting strange sea creatures has transformed him from an ordinary fisherman to an influential ocean ambassador. Through his social media presence, he offers glimpses into a world few people will ever experience firsthand, creating a bridge between deep-sea environments and public awareness.
His approach combines genuine curiosity with a desire to share knowledge. While some of his followers respond with fear to these unusual specimens, Fedortsov often provides educational context about the species he encounters. This combination of entertainment and information has proven highly effective at engaging audiences with marine biodiversity.

Some marine enthusiasts develop such deep connections with aquatic environments that they push human limits to explore them. One remarkable example involved a scientist who refused to resurface after breaking the world record for longest time underwater, demonstrating the profound pull that underwater worlds can exert on those who study them.
The compassion shown toward unfamiliar creatures reflects broader themes of empathy across species boundaries. Just as a veterinarian once dined with a scared shelter dog to encourage it to eat, Fedortsov’s work encourages people to look beyond initial reactions of fear to appreciate the remarkable diversity of marine life.
Other remarkable deep-sea findings
Fedortsov’s Pacific lumpsucker isn’t the only unusual deep-sea creature making headlines. During the same period, marine biologists observed a “black sea devil” (a type of anglerfish) at the surface for the first time near Tenerife, Spain. These rare sightings provide valuable data about species typically confined to depths beyond human access.
The deep ocean remains Earth’s last great frontier, with estimates suggesting we’ve explored less than 20% of our oceans. Scientists believe thousands of marine species await discovery, particularly in extreme environments like hydrothermal vents, deep trenches, and polar waters. Each unusual specimen brings new insights into evolutionary adaptations and ecological relationships.

Climate change and ocean acidification threaten many of these specialized deep-sea communities before we can fully understand them. Rising temperatures and changing ocean chemistry may disrupt the delicate balance that supports creatures like the Pacific lumpsucker, potentially leading to losses of biodiversity we haven’t yet documented.
By sharing images of bizarre marine life, fishermen like Fedortsov contribute to public awareness about ocean conservation. These strange encounters remind us that protecting marine environments preserves not just familiar species but also the weird and wonderful creatures that have evolved in Earth’s most extreme habitats.
