Species diversity in the world's seas
Philippe Rekacewicz, UNEP/GRID-Arendal
There is growing evidence that many marine species are less widely distributed, and therefore more vulnerable to extinction, than previously thought. This graphic shows the diversity of marine mammals, sharks, molluscs, birds, and shrimps and lobsters in the world's marine areas. The data have been modified to show the species diversity of each region as a fraction of the most species-rich region.The maximum number of marine mammals species in a region is 52, sharks 140, molluscs 1114, birds 115 and shrimps and lobsters 210.
