Staff Reporter

KOCHI: The rediscovery of a Jurassic shrimp, thought to have been extinct 50 million years ago, and a living Caribbean fossil that flourished worldwide some 100 million years, are some of the interesting finds of the recently concluded first census of marine life.

The census revealed the richness of marine biodiversity and it took the estimate of known marine species from about 2.3 lakh to nearly 2.5 lakh, adding 20,000 new species to the list..

Each year, around 130 species of fishes are discovered and it is estimated that at least 7.5 lakh marine species remain to be discovered, said Ian Poiner, Chair, International Scientific Steering Committee of the Census of Marine Life International Secretariat.

Microbial life

Talking to mediapersons on the sidelines of a talk on census here on Wednesday, Mr. Poiner said the oceans were also found to be rich in microbial population It is considered that there would be at least 25,000 species of bacteria in one litre of seawater, he said. The talk on ‘Census of marine life - a decade of discovery' was organised by the Centre for Marine Living Resources and Ecology and the National Institute of Oceanography, Kochi region.

The census engaged 2,700 marine scientists from 670 laboratories from more than 80 nations and all continents. More than 9,000 days were spent in sea in more than 540 oceanographic expeditions, he said.

Bar-coding

Nearly 1,00,000 marine species were bar-coded as part of the census. The studies also revealed that the population of species like reef fishes, tuna, shark and whales have depleted by around 90 per cent. The census found more than 6,000 potentially new species and completed formal descriptions of more than 1,200 of them.
