Tamilnadu Affairs
The Western Ghats introduced new butterflies, frogs, fruit flies, and even a freshwater crab in the first four months of 2021.
Xylophis Deepaki, a tiny snake with iridescent scales that is only 20 cm long, has been added to the list.
It was discovered in a coconut plantation in Kanyakumari for the first time.
It has been sighted in a few locations in the southern part of the Western Ghats and is now considered an endemic species of Nadu.
The species is named after Indian herpetologist Deepak Veerappan, who was instrumental in establishing the Xylophiinae subfamily to accommodate wood snakes.

Gk bit : Difference between Chaff and Flares:
Both chaff & flares are defensive countermeasures deployed by using navy aircraft. The cause is to confuse radar-guided or infrared-guided anti-plane missiles fired so that they may want to be diverted.
The Chaff is composed of many small aluminium or zinc lined fibres saved on-board the plane in tubes. In case the plane feels threatened by means of any radar monitoring missiles, chaff is ejected into the turbulent wake of air at the back of the plane.
Flares on being fired grant an alternate strong IR (Infrared) source to heat-seeking anti-air missiles. Thus they are lured away from the aircraft.
