Scientists Discovered A Record Number Of New Ocean Species
Scientists working on the world's largest ocean species discovery mission have announced a record-breaking year, identifying 1,121 new marine species in a single twelve-month period, a 54 percent jump over the previous annual record and a result that researchers are calling a significant step forward in the effort to understand and protect the world's oceans. The discoveries were made through the Nippon Foundation-Nekton Ocean Census, a global initiative involving hundreds of scientists across dozens of research expeditions, and span an extraordinary range of life from corals, crabs, shrimps, and sea urchins to creatures found at depths of more than four miles beneath the ocean surface, where pressure is so extreme and conditions so alien that scientists are continually surprised by what can not only survive there but thrive. Among the most striking finds was a species known as the Ghost Shark Chimaera, a distant relative of sharks and rays discovered in the Coral Sea Marine Park off Queensland, Australia, from an evolutionary lineage that diverged from sharks and rays nearly 400 million years ago, predating the dinosaurs by more than 200 million years. Also discovered were symbiotic bristle worms living inside what researchers described as a glass castle, the intricate silica-made chambers of a glass sponge on volcanic seamounts off the coast of Japan.
Scientists estimate that only about 10 percent of all marine species have ever been formally identified, meaning the ocean remains the largest unexplored ecosystem on the planet and one whose full biological diversity is almost entirely unknown. The Ocean Census was launched specifically to accelerate the pace of discovery, using cutting-edge deep-sea submersibles, environmental DNA sampling, and advanced imaging to reach habitats that were simply inaccessible a decade ago. The program's chief scientist said the record tally is not just a scientific milestone but a reminder of how much of our planet is still waiting to be understood, and that every species added to the list represents both a discovery and a reason to protect the environment in which it was found. The organization has pledged to continue accelerating its work, with an ambitious long-term goal of identifying tens of thousands of new species in the coming decade and building the most complete picture of ocean life that science has ever assembled.
