Try this question from CSP 2018:

Assam Keelback Snake

  • The species is small — about 60 cm long, brownish, with a patterned belly.
  • This particular keelback does not belong to the generalized keelback snake of India but is rather a unique genus (Herpetoreas).
  • It was discovered 129 years ago by Samuel Edward Peel, a British tea planter based in Upper Assam.
  • The snake’s ‘lost’ status has a lot to do with the habitat it occupies — in this case, a lowland evergreen forest.
  • These forests have been selectively degraded during the last 100 years: tea plantations have been made, selective logging has taken place, and many other activities such as oil exploration and coal mining.

Is the snake under threat?

  • Most snakes and other reptiles are categorised as ‘data deficient’ in the IUCN list.
  • There is practically no information available about it and it is difficult to determine its status.
