The Patrick Star Starfish Is Real

There is a creature on the ocean floor that looks like it walked straight out of a Saturday morning cartoon. It is a vivid orange sea star with a rounded, almost goofy shape that bears a striking resemblance to Patrick Star, the beloved sidekick from SpongeBob SquarePants. This is not a costume or a digital render. It is a real biological entity documented in the Mar del Plata Submarine Canyon off the coast of Argentina.

The discovery was part of a massive expedition that yielded 57 new species, a haul that has scientists and the public alike reeling from the sheer novelty of the deep. The identification of this starfish is just the headline act in a much larger story about how little we actually know of our own planet. The team behind this find, led by the Nippon Foundation-Nekton Ocean Census in partnership with the Schmidt Ocean Institute, spent months processing samples from the August 2025 expedition.

Their work resulted in the classification of 20 new copepods, 22 echinoderms, 14 cnidarians, and one scaphopod mollusc. Five of these represent entirely new scientific genera, meaning we are not just finding new animals, but new branches on the tree of life. This collaborative model is crucial because taxonomy is a slow, detailed science that requires fresh eyes and diverse expertise to distinguish a new species from a previously unknown variant.

A Workshop in the Deep

The process of naming these creatures was not a solitary endeavor but a collaborative international effort. An international Species Discovery Workshop brought together 20 taxonomists and early-career researchers from across Latin America and Europe. They gathered to examine deep-sea biological samples primarily from the Schmidt Ocean Institute's Underwater Oasis expedition. This collaborative approach ensures that every specimen receives the rigorous scrutiny needed for accurate scientific classification.

The use of remotely operated vehicles (ROVs) made this possible. The team utilized ROV SuBastian, which is rated to a depth of 4,500 meters, to navigate the dark, high-pressure environment of the canyon. These machines allow scientists to collect samples and observe behavior in situ without the constraints of human diving. The images captured by these vehicles provide the first visual record of these species, many of which have never been seen by human eyes before this expedition.

Working with such specialized equipment allows for a level of detail that was previously inaccessible. The ROVs can maneuver around delicate structures and capture high-resolution footage of organisms in their natural habitat. This technology bridges the gap between the physical collection of samples and the visual documentation required for public engagement and scientific analysis, ensuring that the data is both comprehensive and accessible.

Beyond the Cartoon

While the orange starfish captures the popular imagination, the rest of the discovery is equally fascinating to those who follow marine biology. The list includes a deep-sea holothurian, or sea cucumber, that researchers have named "Loki" due to its prominent horned appendages. There are also newly discovered species of octocorals, sea pens, and stony corals that expand our understanding of how these organisms thrive in such extreme conditions.

The diversity of this find suggests that the Mar del Plata Canyon is a hotspot for endemism, a region where unique evolutionary pressures have produced species found nowhere else on Earth. The presence of a newly discovered pink deep-sea lobster and a sea cucumber with radiating stalks ending in bulbous, translucent spheres adds to the surreal quality of the haul. These are not just generic fish or worms. They are complex, specialized organisms that have adapted to the darkness and pressure of the deep ocean.

The fact that 57 new species were identified in a single workshop underscores the idea that the deep sea remains one of the last great frontiers for biological discovery on our planet. Each organism tells a story of adaptation and survival in an environment that is hostile to most forms of life. The intricate details of their bodies, from the horns of the Loki sea cucumber to the translucent spheres of the other holothurian, reveal the creative power of evolution in the deep.

Why It Matters

Discovering new species is more than a matter of curiosity. It is a measure of biodiversity and a reminder of the fragility of marine ecosystems. Each new species represents a unique set of genetic adaptations that could have implications for medicine, biotechnology, or our understanding of evolution. The five new genera identified in this expedition, spanning corals, sea cucumbers, and crustaceans, suggest that our current taxonomic frameworks are incomplete.

We are still writing the basic outlines of the deep-sea ecosystem. The collaboration between the Nippon Foundation-Nekton Ocean Census and the Schmidt Ocean Institute highlights the importance of international partnerships in scientific research. The data generated from these expeditions is shared openly, allowing researchers worldwide to contribute to our collective understanding. This transparency is vital, as it ensures that the knowledge gained from these expensive and logistically complex missions benefits the entire scientific community.

By sharing data openly, we prevent the fragmentation of scientific knowledge and allow for cross-disciplinary insights. Researchers in different fields can access the same information, leading to a more holistic understanding of marine life. This collaborative spirit is essential for advancing our knowledge and ensuring that the conservation of these newly discovered species is informed by the best available evidence.

The Deep Sea Still Surprises

It is easy to think that we have mapped and cataloged most of the life on Earth. The reality is that the deep ocean, which covers the majority of the planet's surface, remains largely unexplored. The Mar del Plata Submarine Canyon is just one of many such regions where new life is waiting to be discovered. The fact that a creature resembling a cartoon character was found in this specific location is a testament to the unpredictability and richness of the natural world.

As we continue to explore the depths, we are likely to find more surprises, both whimsical and profound. The 57 new species identified in this workshop are a snapshot of a much larger truth. The deep sea is a vast, dynamic, and often bizarre ecosystem that defies our expectations. The discovery of the Patrick Star-like sea star is a reminder that nature is often stranger and more creative than any human imagination could devise.

This ongoing exploration challenges our assumptions about what life can look like and where it can thrive. It encourages a renewed sense of wonder and a deeper appreciation for the complexity of our planet. As technology advances, we will undoubtedly uncover even more hidden gems in the deep, each one adding a new chapter to the story of life on Earth.
