Census of Marine Life | WWF

Incredible biodiversity that lies just below the surface

Representing the most comprehensive and authoritative answer yet to one of humanity’s most ancient questions – “what lives in the sea?” – Census of Marine Life scientists released an inventory of species distribution and diversity in key global ocean areas.

Scientists combined information collected over centuries with data obtained during the decade-long Census to create a roll call of species in 25 biologically representative regions – from the Antarctic through temperate and tropical seas to the Arctic.

Our oceans are precious

The Census of Marine Life provides a glimpse into a vast and diverse marine world that we rarely see. Unfortunately much of this marine life is increasingly threatened by pollution, bycatch, development and climate change.
