    • Skinks are non-venomous, highly alert, agile and fast moving and actively forage for a variety of insects and small invertebrates.
    • They have a prominent role in maintaining ecosystems, however, not much is known about their breeding habits, and ecology because identification of the species can be confusing.
    • In India skinks are found in all kinds of habitats in the country, from the Himalayas to the coasts and from dense forests to the deserts.
  • The Study:
    • It gives a phylogenetic (evolutionary development) and bio-geographical analysis of distribution of these species in all the 11 bio-geographic zones of India.
    • India is home to less than 4% of the skinks across the globe. 62 species of skinks are found in India and about 57% of them (33 species) are endemic.
    • India is home to 16 genera of skinks, four of which are endemic. The four genera of skinks are:
      • Sepsophis: Sepsophis punctatus is endemic to the northern part of Eastern Ghats
      • Barkudia: They are limbless skinks found in the hills and coastal plains of the eastern coast.
        • Barkudia insularis is believed to be found only in the Barkud Island in Chilka lake in Odisha.
        • Barkudia melanosticta is endemic to Visakhapatnam.

      • Ristella: They are also known as Cat skinks and endemic to the southern part of Western Ghats.

Zoological Survey of India

  • The Zoological Survey of India (ZSI), a subordinate organization of the Ministry of Environment, Forest and Climate Change was established in 1916.
  • It is a national centre for faunistic survey and exploration of the resources leading to the advancement of knowledge on the exceptionally rich faunal diversity of the country.
  • It has its headquarters at Kolkata and 16 regional stations located in different geographic locations of the country.
