The group is distinguished from all other cobras due to the presence of a row of subocular scales separating the eye from the supralabials.

This cobra species can easily be identified by its relatively large and quite impressive hood, which it expands when threatened.

[9] Maximum size attained by this species is just a bit over 2.0 metres (6.6 ft), but these are rare cases.

The longest recorded female was slightly shorter at 2.18 metres (7.2 ft) and was found 25 kilometres (16 mi) south of Shakawe, Botswana.

[10] Young specimens are yellowish to light brown in colour, above and below, dorsally with dark scale margins forming a pattern of irregular transverse lines and a black band that circles the neck.

As they mature into adulthood, this species gradually darkens to a darker brown colour, while the band on the neck fades away.

Although usually found at low altitudes, it has on occasion been observed at elevations of 2,000 metres (6,600 ft) above sea level.

[14] The Anchieta's cobra is a terrestrial or ground-dwelling species, but it may occasionally be found in small shrubs.

During the day it is often seen basking in the sun near a preferred retreat, usually an abandoned termite mound, a hole in a rock, hollow tree, and shrubs or under dense vegetation.

[11] This species, like other cobras, will lift its forebody off the ground, spread its impressively broad 10 to 12 centimetres (3.9 to 4.7 in) hood and assume a defensive posture when provoked, however, it will flee when given the chance.

[15] This species has been known to feign death as defence mechanism against possible predators or when it is cornered, although it does not display this behaviour as often as the rinkhals (Hemachatus haemachatus) does.
