LD50: 0.164
This is common aquatic snake species found in Asian and Australian warm waters. It inhabits open sea as well as river mouths and estuaries. It is nicely camouflaged for the aquatic environment, being grayish on the dorsal (back) side with lighter and darker bands and lighter on the ventral side (belly). It is highly toxic and will not hesitate in defending itself when feeling threatened. Bites are common in fishermen who catch them in nets and they can be fatal, which makes it one of the most poisonous snakes in India.
