Seeing Deeply Into the Sea’s BiodiversityResults from the decade-long Census of Marine Life are pouring in, providing insights into what lives where in the world’s oceans

M A R I N E B I O LO G Y

For the past 10 years, scientists from

80 nations have been creating the Cen-

sus of Marine Life (Science, 2 June 2000,

p. 1575; 31 October 2003, p. 773).

Derek Tittensor of Dalhousie Univer-

sity in Halifax, Canada, and colleagues

have now analyzed more than 6.5 mil-

lion entries from the census databases,

as well as other data for 11,500 marine

species to create a map (top right) of

diversity hot spots. Corals and coastal

fishes are most diverse in Southeast

Asia, as indicated by the outlined squares

in the map, the team reported online

28 July in Nature.

Another analysis, drawn from field

surveys and literature reviews by 360 sci-

entists, appears in a series in the 2 August

PLoS ONE. It looks at species diversity

in 25 regions of the world and comes

up with a global average of what types

of species populate the oceans (see pie

chart). The proportions of species that

inhabit particular waters change accord-

ing to location.
