10. Indian cobra (Naja naja)
LD50: 0.35
The first snake on our list of most poisonous snakes in India that belongs to the notorious group of “Big four” Indian snakes. Indian cobra is perhaps the first species that comes into one’s mind when thinking of cobras because of the recognizable pattern on the back of the hood – spectacle or eye shaped marks. It is a thick species of medium size (from 3-5 feet of length). This cobra is highly venomous and causes many deaths in humans.
