The Ocean Census, a joint mission between the Nippon Foundation and Nekton, has identified 1,121 potentially new-to-science marine species in its third year. This includes discoveries like a worm living inside a 'glass castle' sponge and a ghost shark. Scientists have now catalogued more than 2,000 new species since the project began in 2023.
Facts First
- The Ocean Census identified 1,121 new marine species in its third year, which ran from April 2025 to March 2026.
- The project has catalogued over 2,000 species since its launch in April 2023.
- Recent discoveries include a worm living symbiotically in a glass sponge, a ghost shark off Australia, and a ribbon worm off Timor-Leste.

What Happened
The Ocean Census concluded its third year of work, during which scientists identified 1,121 potentially new-to-science marine species. Michelle Taylor, head of science at the Ocean Census, stated that roughly half of the project's total discoveries—now over 2,000 species—were found during this period. Specific discoveries include a new species of polychaete worm found off Tokyo, a new ghost shark species off Queensland, Australia, and a new ribbon worm off Timor-Leste.
Why this Matters to You
This cataloguing effort expands humanity's fundamental understanding of life on Earth. The discoveries may lead to new insights into deep-sea ecosystems and symbiotic relationships, which could inform future conservation strategies. A better map of ocean biodiversity could help guide sustainable management of marine resources.
What's Next
The Ocean Census project is likely to continue its deep-sea exploration missions to uncover more unknown species and fill gaps in our knowledge of marine life.
