As many as 539 new species of plants and animals were discovered by scientists and taxonomists in the country in 2017, say publications from two major survey organisations: the Zoological Survey of India (ZSI) and the Botanical Survey of India (BSI).

Released on Tuesday, World Environment Day, Animal Discoveries, 2017 from the ZSI lists 300 new species of fauna. Plant Discoveries, 2017 lists 239 new flora species.

Besides these discoveries, the biodiversity in the country recorded another 263 species with 174 new records of animals and 89 of plants found. The number of discoveries of sub-species and varieties takes the number of floral discoveries to 352.

New fossils

The highlight of the animal discoveries was a new fossil reptilian species — Shringasaurus indicus — recorded by scientists of the Kolkata-based Indian Statistical Institute. The important discoveries include a frog species, Nasikabatrachus bhupathi , with snout-shaped nose like a pig and named after Indian herpetologist S. Bhupathy; and a snake, Rhabdops aquaticus , discovered from the northern Western Ghats and deriving its name from the Latin word for water in reference to its presence in freshwater bodies.

With these discoveries, the number of animal species in India stands at 1,01,167, which is 6.45% of the faunal species found in the world. The number of plant species has increased to 49,003, which is 11.4 % of the world flora.
