Description
Context: The harmless, insectivorous lizards are found across the country in every bio-geographic zone.
Skinks
- With long bodies, relatively small or no legs, no pronounced neck and glossy scales, skinks are common reptiles around homes, garages, and open spaces such as sparks and school playgrounds, and around lakes.
- Although they are common reptiles and have a prominent role in maintaining ecosystems, not much is known about their breeding habits, and ecology because identification of the species can be confusing.
- Skinks are highly alert, agile and fast moving and actively forage for a variety of insects and small invertebrates.
- The reduced limbs of certain skink species or the complete lack of them make their slithering movements resemble those of snakes, leading people to have incorrect notion that they are venomous.
- This results in several of these harmless creatures being killed.
Skinks of India publication
- A recent publication by the Zoological Survey of India (ZSI) reveals that India is home to 62 species of skinks and says about 57% of all the skinks found in India (33 species) are
- The publication, Skinks of India, was released by the Union Minister of State, Ministry of Environment Forest and Climate Change.
- “It is the first monograph on this group of lizards, which are found in all kinds of habitats in the country, from the Himalayas to the coasts and from dense forests to the deserts,”
- A lot of work is done on other groups of reptiles like snakes or geckos, skinks are an ignored species.
Wide collaboration
- The publication is a result of four years of work and study of over 4,000 specimens in all 16 regional centres to makes an attempt to ‘redescribe’ all the 62 species with their taxonomic identification keys, distributional maps, habits, habitat and breeding biology.
- The Western Ghats are home to 24 species of which 18 are endemic to the region.
- The Deccan Peninsular region is home to 19 species of which 13 are endemic. There are records of 14 skink species from the northeast of which two species are endemic.
- With 1,602 species of skinks across the world, making it the largest family of lizards, their occurrence in India is less than 4 % of the global diversity.
Celebrating skinks, Zoological Survey of India lists 62 species
- Of the 16 genera of skinks found in India, four genera are endemic.
- Sepsophis (with one species)and Barkudia (with two species) are limbless skinks found in the hills and coastal plains of the eastern coast.
- Barkudia insularisis believed to be found only in the Barkud Island in Chilka lake in Odisha.
- Barkudia melanosticta is endemic to Visakhapatnam.
- Sepsophis punctatus is endemic to the northern part of Eastern Ghats.
- Five species of Kaestlea (blue-tailed ground skinks) are endemic to the Western Ghats and four species of Ristella (Cat skinks) also endemic to the southern part of Western Ghats.
