The mystery of the oceans revealed

Our oceans cloak over 70 percent of the planet, brimming with astonishing lifeforms yet shrouded in mystery. Despite decades of exploration, only a fraction of marine species are known. The Nippon Foundation-Nekton Ocean Census estimates that 90 percent of the ocean’s inhabitants have yet to be discovered.

Revolutionizing marine discovery

Ocean Census stands at the forefront, pushing the boundaries of marine biology through a concerted effort to catalog oceanic life. In just one year, from April 1, 2025, to March 31, 2026, their researchers have unearthed 1,121 new marine species. This achievement stems from 13 exploratory missions and nine intensive species discovery workshops, drawing expertise from top-tier scientists worldwide.

“Many species might vanish before we even have the chance to document them,” notes Dr. Michelle Taylor, the Head of Science for Ocean Census. She emphasizes the urgency of this work: understanding and safeguarding ocean biodiversity is a time-sensitive endeavor. Every new species enriches our understanding of marine ecosystems and underscores their vital role in sustaining our planet.
