The Black-Necked Spitting Cobra (Naja nigricollis) is a medium-sized African spitting
cobra. It is an elapid – a snake with fangs.
The Black-Necked Spitting Cobra is
mainly black, but its colour varies. Some are pale grey with a yellow or
reddish ventral side with a broad, black neck band, often with an orange bar on
the neck. Others can be yellowish-brown without the bandings around the neck
and the reddish colour on the belly, whereas others are deep reddish-brown or
olive brown.
They have
21-23 dorsal scales at the mid-body, 182-196 ventral scales, and
54-66 subcaudal scales.
The Black-Necked Spitting Cobra can
grow to a length of 1-2 metres (3.3 and 6.6 feet).
They prey
on small rodents, such as small rats and mice, but also birds,
lizards, eggs and other snakes.
Like
other spitting cobras, it can eject venom from its fangs. The venom can cause
permanent blindness if it enters a person’s eyes.
The Black-Necked Spitting Cobra is
common and widespread in Africa. It likes savanna and semidesert regions,
as well as locations near rivers. Like other cobra species, the Black-Necked Spitting Cobra may live
in abandoned termite mounds, rodent holes or tree trunks. They are
excellent tree climbers.
They can
be nocturnal (active at night) or diurnal (active during the day).
Like
other cobra species, the Black-Necked
Spitting Cobra is oviparous, which means that it lays eggs. Females
lay 10-15 eggs, which take about 60-70 days to hatch. At birth, the young snakelets
are about 20-25 centimeters (7.9 to 9.8 inches) in length and are
completely independent.
