How Many Species Live in the Sea?
How many species are there in the sea? Some 230,000 recorded so far, all of which will soon be available to anyone at the click of a mouse.
The World Register of Marine Species is launched today by the Census of Marine Life. Once complete,it will provide the first definitive (权威性的)list of all known species in the worlds oceans. The Register is freely accessible online and includes descriptions of the species ancf photos. It will allow both the public and scientists to identify species they come acrossandeasilyrecogniseentirelynewspecies.
Until now censuses have been incomplete, focusing on single species or regions, making proper assessment of the impact of humans on oceans difficult. “ Convincing warnings about declining populations of fish and other marine species must rest on a valid census,” says Mark Costello of the University of Auckland, co-founder of the World Register.
Jesse Ausubel of the Sloane Foundation, which funds the Census of Marine Life, says he was first struck by the need to catalogue marine species in 2000, when he realised the UN Environment Programme’s Global Biodiversity Assessment had little information on what lived in the sea. Ausubel asked the marine life specialist, Frederick Grassle of Rutgers University, US, how many species there were in the sea. He was told that the best estimate was between 1 and 10 million.
“ I asked him if he could at least give me a list of the species that were known at the time" says Ausubel. Grassle was embarrassed to admit he could not. u How could there not be a list in the year 2000 of what we knew to live in the oceans?” marvels Ausubel.
Since then, the Census of Marine Life has worked to establish such a list. With the help of experts worldwide, they are carefully reviewing and compiling published records of marine species. Much of the work has focused on identifying species given different names that are in fact the same.
So far, the catalogue contains 122,000 species, about half the estimated 230,000 known species. There are still millions more ocean species to be discovered. But how about Grassle’s estimate of between 1 and 10 million total marine species?
“ We think that a million is reasonable,” says Ausubel, adding that experts have little idea what the upper limit could be.
The whale has been found to have different names in different parts of the world.
