The Monocled Cobra is large species of elapid. It is found in Bangladesh, Bhutan, Cambodia, China, India, Laos, Thailand, West Malaysia, Myanmar, Nepal, and Vietnam. Adult males can grow up to 2.3 m length and weight up to 1.8 kg. The head is barely distinct from the neck and they have a cylindrical body. The coloration and pattern are variable, the dorsal surface may be yellow, brown, grey, or blackish and with or without ragged or clearly defined cross bands. Specimen found in SBR are mostly dark or black with the classic monocle mark on their hood. Snakes reach maturity in their third year of age and their clutch size ranges from 12-45 eggs. Most literature states that this is non spitting species, but I have observed this behaviour on two occasions. In SBR Monocled Cobras are found in deep forest, around research station as well as in the villages. The median lethal dose (LD50) of its venom is 0.28-0.33 mg/g of mouse body weight.
