A Global Mission

The Ocean Census is a global mission to discover, document and share the diversity of life in our ocean — before it’s lost.

Discover  Life

The Nippon Foundation-Nekton Ocean Census mission is to accelerate
the discovery of ocean life to sustain and advance life on Earth.

ONLY 10%

of Ocean Life has been Discovered

The loss of ocean life is an existential crisis, but we have a window of opportunity—perhaps a decade—to make a significant difference.

Progress Since 2023

800+ new species discovered

10+ expeditions in under-surveyed regions

27 workshops & awards accelerating species discovery

1000+ scientists & 500+ institutes contributing taxonomic expertise

10,000+ media features about the Census & species discovery

Why
it
matters

Earth is the only known place in the Universe where there is complex biology. Ocean life has evolved over four billion years and is our planet’s superpower making all life on Earth possible – giving us our atmosphere, regulating our climate, feeding us and providing cures for our diseases.

Currently no more than 10% of ocean life is known, far less is protected and much is under threat.

Accelerating the discovery of ocean life advances fundamental ocean science, empowers marine conservation and fuels innovation.

To understand life, and sustain it, we must first discover it.

THE CENSUS IN ACTION


EXPLORE THE MISSION DISCOVER OCEAN LIFE

Expeditions

Our expeditions explore some of the ocean’s most under-surveyed, biodiverse and ecological regions. They focus on collecting specimens for scientific analysis and contribute vital data to the global marine species record. Click a location to learn more about each mission.

Species Discovery Workshops

These workshops unite taxonomists around the world to identify and catalogue marine species, using specimens collected from expeditions and museum collections. Select a workshop location to explore its outcomes.

Limpet

Found

Up to 50m
South Africa’s Indian Ocean Coast

Interesting fact

Discovered at a depth of 3,053m in the Jøtul Vent Field of the Norwegian-Greenland Sea, this deep-sea limpet (Cocculina sp.) is expanding scientific knowledge of the Arctic Ocean—Earth’s least documented and least biodiverse ocean.

SQUAT LOBSTER

Found

407m Depth
On Expedition: Schmidt Ocean Institute Unexplored Seamounts of the Salas y Gómez Ridge

Interesting fact

This newly discovered squat lobster (Galathea sp.) is the first of its genus recorded in the southeastern Pacific Ocean near Easter Island (Rapa Nui).

GUITAR
SHARK

Found

Approx. 200m depth
Tanzania

Interesting fact

This newly identified guitar shark, found off Tanzania, is only the 38th known species of its kind and belongs to one of the ocean’s most threatened vertebrate groups.
