The ocean, covering 70% of Earth’s surface, remains one of the least explored frontiers. Despite its vastness, scientists estimate that only about 10% of marine life has been documented, leaving millions of species yet to be discovered. Traditional methods of marine exploration, often slow and resource-intensive, have contributed to this knowledge gap. However, recent advancements in technology and international collaboration are beginning to change this narrative.
The need to explore the ocean: New resources could be hidden underwater
The urgency to uncover marine biodiversity has never been greater. Many species face threats from climate change, pollution, and habitat destruction, making timely documentation crucial. Delays in identifying new species can hinder conservation efforts and our understanding of marine ecosystems. Accelerating the discovery process is essential to inform effective protection strategies and ensure the survival of countless marine organisms.
In response to these challenges, a groundbreaking initiative has emerged. Launched in April 2023, this global project aims to rapidly identify and catalog marine species. Utilizing advanced technologies and a vast network of scientists, the initiative has already made significant strides. Among its recent achievements is the discovery of over 800 new marine species, highlighting the untapped potential of our oceans. These findings underscore the importance of continued exploration and the need for innovative approaches to marine science.
Multiple findings in the depths of the sea: sharks, corals, and venomous animals
A guitar-shaped shark and a venomous deep-sea snail are among 866 species recently discovered to explore the ocean’s hidden life before it’s too late. The discoveries came from divers, piloted submersibles, and remotely operated vehicles during 10 sea expeditions.
Ocean Census, a global alliance focused on protecting marine life, confirmed that all of these species are new to science and released its first major update since launching in 2023. The 10-year project was designed to fill the massive gaps in knowledge about life in the sea’s depths.
Michelle Taylor, a coral expert at the University of Essex and a principal investigator with the alliance, explained that only a small fraction of marine species have been identified so far. She noted that the alliance is documenting an extraordinary variety of life, from sharks and pipe fish to snails and corals.
Not easy to find these animals: Over a week sailing to study these unknown species
The newly discovered species were found at depths ranging from just 3 feet (1 meter) to over 3 miles (4,990 meters). More than 800 scientists from 400 institutions contributed to the analysis through the Ocean Census Science Network. Taylor’s expedition was expected to yield additional species, including a coral that appeared to be previously unknown.
The researcher emphasized the remoteness of the region, which required an eight-day sail from southern Chile and sees few visitors. Other expeditions uncovered new species such as limpets and sea stars in the polar waters of the Norwegian-Greenland Sea at depths of 10,000 feet (3,053 meters). These creatures survive in extreme conditions, from near-freezing waters to zones heated by hydrothermal vents reaching 572 degrees Fahrenheit (300 °C).
The most impactful discovery is that it is already helping medicine
One of the most impactful finds was a predatory snail, the Turridrupa magnifica, which uses specialized teeth to inject venom into its prey. Related species have already contributed to medical advances, including pain treatments.
New tools, like genetic sequencing of environmental DNA and real-time imaging, are speeding up species identification. However, collecting physical specimens remains essential for scientific confirmation, which can be a slow process. Formally describing a species can take years, and many of the organisms identified by Ocean Census have not yet been named. The alliance’s goal is to accelerate discovery, aiming to document 100,000 new species over the 10-year project.
