"In the last one year we have discovered 133 new species in 19 categories - from one-cell organisms to fish, crabs, a bird and many more in the last one year," director of Zoological Survey of India K.Venkataraman told PTI.
The most significant discovery was that of a flightless bird in the Great Nicobar Islands of Andamans as a new bird species is rarely found.
"Discovery of new animal species such as one-cell organisms is common, but discovery of a new bird is very uncommon and rare. This bird species found by ZSI is yet to be named as the scientists have managed to just have a photo. We are trying to trap one of them and study it," Venkatraman said.
The scientists have also discovered two new species of amphibians, 19 species of fishes, two species of reptiles, two species of crabs, four species of spiders, 66 species of insects and many other species including microscopic cell organisms, mites, mollusca and many others.
At least one species of insect, three species of flies, two species of mites and one species of fish were found in Kolkata and some districts of Bengal, the ZSI director said.
