Exploring Biodiversity: 20 New Species Found in Remote Southeast Pacific Seamounts
In the vast expanse of the southeastern Pacific Ocean, nestled some 1,400 kilometers off the coast of Chile, lies a hidden world teeming with rare deep-sea creatures. These mysterious beings drift gracefully along the flanks of a 3,100-meter-tall undersea mountain, where a vibrant garden of sponges and corals thrives in the depths. This remote region, known for its seamounts, has recently captivated the attention of scientists and explorers alike, unveiling a treasure trove of biodiversity waiting to be discovered.
The intersection of the Nazca and Salas y Gómez Ridges, where these seamounts are located, has emerged as a deep-sea biodiversity hot spot, drawing researchers from around the globe to unravel its secrets. A recent monthlong survey conducted by the Schmidt Ocean Institute has shed light on this enigmatic underwater world, unveiling not only a never-before-seen seamount but also revealing numerous species of sea life that may be new to science.
The discovery of the mammoth seamount, standing tall at thousands of meters high with its summit submerged 994 meters below the ocean surface, came as a surprise to the expedition team. Initially identified through low-resolution satellite imaging as a mere bump on the seafloor, the seamount proved to be a thriving ecosystem brimming with life. Using a diving robot to explore the seamount and nine others in the vicinity, researchers were met with a breathtaking scene—a garden of sponges and ancient corals stretching across an area twice the size of a basketball court.
While the density of corals in this deep-water reef may not rival that of shallow water reefs, which are known to be densely packed with corals, the sight was nonetheless impressive. Jyotika Virmani, executive director of the Schmidt Ocean Institute, describes the underwater garden as a mesmerizing display of nature’s beauty, showcasing the resilience and diversity of marine life in these remote seas. Among the remarkable creatures encountered during the expedition was the ghostly white Casper octopus, named for its uncanny resemblance to the friendly cartoon specter Casper.
The sighting of the Casper octopus, previously known only from the North Pacific and yet to be formally described by scientists, highlighted the unique biodiversity of the region. Another notable discovery was the first-ever footage of a living Promachoteuthis squid, a mysterious deep-sea inhabitant that had only been observed in nets before. These findings, along with the encounter of 20 potentially new species, have added to the growing list of unique marine life found in the seamounts of the southeastern Pacific.

The Hidden World of Seamounts
Seamounts, underwater mountains that rise from the ocean floor, have long been known to harbor unique ecosystems and biodiversity. These submerged giants serve as oases of life in the deep sea, providing habitats for a wide range of species that are adapted to the harsh conditions of the ocean depths. The seamounts in the southeastern Pacific, located at the intersection of the Nazca and Salas y Gómez Ridges, represent a particularly rich and diverse environment that has only begun to be explored.
The recent expedition by the Schmidt Ocean Institute uncovered the hidden world of these seamounts, revealing a stunning array of marine life that had previously eluded discovery. From colorful sponges and corals to elusive octopuses and squids, the seamounts proved to be a treasure trove of biodiversity waiting to be unveiled. The team’s use of advanced diving robots allowed them to capture rare footage of these deep-sea creatures in their natural habitat, providing valuable insights into the unique ecosystems that thrive in the depths of the southeastern Pacific.
Unveiling New Species
One of the most exciting aspects of the expedition was the discovery of 20 potentially new species that had never been documented before. These enigmatic creatures, ranging from sea anemones and urchins to shrimp and squat lobsters, may represent previously unknown forms of life that have evolved to thrive in the extreme conditions of the seamounts. The team’s findings have added to the growing body of evidence suggesting that the southeastern Pacific is a hotspot of biodiversity, with untold numbers of species waiting to be identified and studied.
Among the most intriguing discoveries was a fossil that may belong to a new species of ancient whale, hinting at the region’s rich evolutionary history. While further research is needed to confirm the identity of this fossil, its presence underscores the importance of continued exploration and conservation efforts in the remote seas of the southeastern Pacific. By uncovering new species and shedding light on the unique ecosystems of the seamounts, the expedition has highlighted the need to protect these fragile environments for future generations.
Exploring the Unknown
The exploration of the seamounts in the southeastern Pacific represents a journey into the unknown, a quest to unravel the mysteries of the deep sea and uncover the secrets of the underwater world. With each new discovery, scientists are gaining a better understanding of the complex interactions that shape marine ecosystems and the vital role that these remote habitats play in supporting life on Earth. By venturing into the depths of the ocean and shining a light on its hidden wonders, researchers are expanding our knowledge of the natural world and inspiring awe and wonder in all who follow their journey.
As we continue to explore the remote seas of the southeastern Pacific and discover new species and ecosystems, it becomes increasingly clear that the ocean holds endless surprises and untold treasures waiting to be revealed. The seamounts, with their towering peaks and vibrant marine life, stand as testaments to the resilience and diversity of life on Earth, reminding us of the interconnectedness of all living things and the importance of preserving our planet’s precious resources for future generations.
