Over 800 new marine species have been discovered through the Ocean Census, a global initiative aimed at accelerating marine life exploration. This significant achievement was announced on March 13, 2025, following two years of collaborative efforts involving scientists, governments, and institutions from around the world.
- Over 800 new marine species discovered.
- Ocean Census involved 400 participating institutions.
- United Nations treaty to protect high seas.
- Guitar shark identified off Mozambique and Tanzania.
- Turridrupa sp gastropod uses venomous teeth.
- Deep-sea sea star crucial for nutrient recycling.
The Ocean Census, founded in April 2023 by the Nippon Foundation and Nekton, has made significant strides in marine biodiversity research. Over 400 institutions and 93 scientists participated in expeditions and workshops, which included 10 global expeditions and eight Species Discovery Workshops. The alliance aims to expedite the identification and registration of new species, a process that can take up to 13.5 years.
Key findings from the Ocean Census include:
- Guitar Shark: Discovered at depths of 200 meters off Mozambique and Tanzania, this species is part of a family that is among the most threatened vertebrate groups.
- Turridrupa sp Gastropod: Found at depths of 380-400 meters in the South Pacific, this predator uses venomous teeth to capture prey.
- Tylaster sp. Sea Star: Located at depths of 2770-3575 meters in the Arctic, this species plays a vital role in nutrient recycling.
Despite the vastness of the oceans, it is estimated that only about 10% of marine life has been documented to date. The Ocean Census aims to address this gap in knowledge and enhance conservation efforts. In 2023, United Nations members agreed on a treaty to protect biodiversity in the high seas, with a goal of conserving 30% of the world’s oceans by 2030.
The discoveries made by the Ocean Census highlight the urgent need for marine conservation and the importance of collaborative efforts in understanding and preserving ocean life. As new species are identified, the potential for developing targeted conservation methods increases, ensuring that these newly discovered species are protected for future generations.
