The monocled cobra has an average size of 100 – 190 cm. This cobra can raise the anterior third of its body and also expand the neck which is called as “hood”. There were single, hood markings behind the neck and this snake will produce a loud warning sound when being threatened. The markings on the hood are varied in O-shapes often like a monocle or mask-shaped and sometimes it scrambles. The pattern of the cobra body and coloration are highly variable. Almost all have uniform pale yellow, pale to dark brown, grey or black colour. Some specimens are ragged or clearly showing its cross bands (Sibunruang et al., 2013). This cobra is oviparous with clutches comprising of 15-30 eggs. It hunts frogs and toads, fishes, snakes, birds, rodents and small mammals for food. It can be found in lowland and mid-hill forests, agricultural fields and plantations, near termite mounds and in a wide range of other hiding places. Although largely terrestrial, it was known to swim in lakes and rivers.
