By Manus AI
The world beneath the waves remains one of the last great frontiers of exploration on our planet. This past week has proven that the ocean's depths still hold countless mysteries waiting to be uncovered. From the abyssal plains of the Central Pacific to the deep waters of the Mediterranean Sea, researchers and explorers have documented an array of bizarre, rare, and fascinating aquatic creatures. Join us as we cast our nets wide to bring you the most unusual marine discoveries from around the globe over the last seven days. Whether you are an avid angler sharing tales on nyangler.com or simply a lover of the marine world, these stories are sure to captivate your imagination.
The Elusive Goblin Shark Filmed Alive in the Wild

In a monumental achievement for marine biology, scientists have published the first confirmed live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep ocean habitat. Often referred to as "living fossils," goblin sharks are the sole surviving representatives of a lineage dating back nearly 125 million years. Known for their ghostly pale or pinkish hue, elongated snout (rostrum), and terrifying jaws that can slingshot forward to snatch prey, these creatures are the stuff of deep sea legend.
Until recently, live goblin sharks had only been observed after being hauled to the surface by fishing lines, where they tragically succumbed to the change in pressure shortly after. However, newly released research details two incredible encounters. In 2019, a remotely operated vehicle (ROV) from the EV Nautilus captured fleeting footage of a goblin shark near Jarvis Island in the Central Pacific. Then, in 2024, a baited camera on a bottom lander filmed another individual along the slope of the Tonga Trench.
The Tonga Trench sighting occurred at a depth nearly 700 meters deeper than the species was previously known to inhabit, setting a new depth record for the entire order of mackerel sharks. Furthermore, these Central Pacific sightings represent a massive geographic range extension for the species, which was previously thought to reside primarily off the coasts of Japan, Australia, and the western United States. These observations highlight how much we have yet to learn about the deep sea and the incredible creatures that call it home.

A Deep Sea Menagerie: 31 Haunting New Species Discovered Off Brazil

The midwater region of the ocean, a vast and dimly lit expanse between the sunlit surface and the seafloor, is the largest habitat on Earth. It is also one of the least understood. Recently, an international team of scientists aboard the Schmidt Ocean Institute's research vessel Falkor (too) embarked on an expedition off the coast of Brazil. Utilizing cutting edge, non invasive imaging technologies, they confirmed the discovery of 31 previously undescribed species in a matter of days.
The midwater menagerie they uncovered is nothing short of otherworldly. The team documented hypnotically beautiful gossamer worms (Tomopteris), comb jellies propelled by glittering appendages, and tadpole like larvaceans that construct balloon like 'houses' out of mucus to trap food. Perhaps most striking were the siphonophores, alien looking colonial invertebrates composed of numerous specialized clones that function together as a single organism.
What makes this expedition particularly groundbreaking is the technology employed. Deep sea fauna are often soft and gelatinous to withstand extreme pressures, making them highly susceptible to damage from traditional sampling methods. To overcome this, researchers utilized advanced laser scanning instruments like DeepPIV and EyeRIS to create 3D images of the creatures without removing them from their environment. They even achieved a first of its kind feat by using a specialized microscope at sea to view the living cellular structures of a single celled microbe. This non destructive approach represents the future of marine science, allowing us to study delicate deep sea life in all its haunting glory.
A Ghost Diver's Surprise: Mediterranean Great White Shark Caught on Film

While exploring a shipwreck over 130 feet below the surface between Sicily and Tunisia, volunteer diver Derk Remmers experienced an encounter most divers only dream of or dread. Remmers, working with the Ghost Diving Foundation to remove abandoned fishing nets, came face to face with an adult great white shark.
This encounter is extraordinary for several reasons. To Remmers' knowledge, this may be the first time a great white shark has been filmed underwater in the Mediterranean Sea in over 40 years. Great white sharks in this region are considered critically endangered by the IUCN, having suffered extreme population declines due to decades of coastal and industrial overfishing.
The context of the sighting is equally poignant. Shipwrecks often act as artificial reefs, attracting diverse marine life. However, when discarded fishing gear, known as "ghost nets," snag on these wrecks, they become deadly traps for the very animals they attract. Remmers and his team were there to clear these hazards. His incredible footage serves as a powerful reminder of the majestic life that still exists in the Mediterranean and underscores the urgent need to protect these vulnerable apex predators from preventable threats like ghost nets and bycatch.
The Anglerfish with "Feet": Sladenia schaefersi Astounds Researchers

In a video that has recently resurfaced and captivated the internet, researchers from NOAA Ocean Exploration documented an encounter with one of the strangest creatures in the deep: Schaefer's anglerfish (Sladenia schaefersi). Filmed in the Gulf of Mexico at depths between 900 and 1,200 meters, this bizarre fish looks less like a typical aquatic predator and more like a living rock.
When the NOAA team first spotted the anglerfish, its mottled, textured skin provided such perfect camouflage that they initially mistook it for a sponge. However, as the camera drew closer, the true nature of the animal was revealed. What makes Schaefer's anglerfish truly remarkable are its modified pectoral fins, which function almost exactly like feet. The fish uses these stout, leg like appendages to prop itself up on the rocky seafloor, waiting patiently in ambush.
Like other anglerfish, Sladenia schaefersi is equipped with a lure to attract unsuspecting prey. Its incredible camouflage, combined with its ability to "stand" motionless, makes it a formidable, albeit highly unusual, deep sea hunter. This encounter remains one of the few times this elusive goosefish species has ever been filmed alive, providing a rare glimpse into the bizarre adaptations that have evolved in the dark depths of the ocean.
Conclusion
The discoveries of the past week serve as a profound reminder of the ocean's vastness and the incredible diversity of life it sustains. From the ghostly goblin shark expanding its known territory to the "walking" anglerfish of the Gulf, these bizarre and fascinating creatures challenge our understanding of biology and adaptation. As we continue to develop new technologies to explore the deep without causing harm, as demonstrated by the Schmidt Ocean Institute off the coast of Brazil, we can look forward to even more astonishing revelations.
These findings also highlight the fragility of marine ecosystems. The rare sighting of the Mediterranean great white shark amidst deadly ghost nets is a stark call to action for conservation efforts. Whether you are an oceanographer, a conservationist, or an angler casting a line on nyangler.com, the preservation of these incredible habitats and the strange, wonderful creatures within them is a responsibility we all share. Until next week, keep exploring and keep casting!
