Identification
The Cape cobra has a wide colour variation ( varies from a
golden yellow to an almost black colour); however a juvenile specimen can be
identified by a brown band on their hood. The snake is most easily identified by its
particularly aggressive defensive posture which it adopts at the slightest
provocation. This snake is also noted for being highly active and very fast
moving. It reaches an average length of 1.2 meters but can reach 2
meters.
Distribution and habitat
This species' distribution is restricted to the
Western Cape, Eastern Cape, Northern Cape, Free State, Botswana and Namibia.
its primarily inhabits dry sandy areas ( e.g. the Karoo) , semi-urban areas (
e.g. informal settlements), disused termite mounds or rodent burrows and has
been seen climbing trees.
Food
Prey consists mainly of
rodents
(e.g.
rats and mice) but also includes lizards, other snakes, frogs and toads. It
also eats birds, particularly young birds and eggs in nests. For instance, it
preys extensively on
Sociable weavers.
Predators, parasites and disease
This snake is primarily eaten by
Herpistidae (e.g.
meerkats and
mongooses),
honey badgers,
birds of prey (particularly
secretary birds and
snake eagles), It also common for it to be preyed on by other snakes (including its own species).
Reproduction
Mating takes place between September and October , females
lay their eggs between December and January , They normally lay between 8 and 20
eggs in a suitable underground cavity such as a
termite mound or
rodent burrow.
Longevity
It has a relatively long life span (one specimen in
San Diego Zoo lived for over 15 years).
Medical importance
Has a very powerful and fast acting neurotoxic venom ,
It is in fact more powerful than any other cobra venom in
Africa. A bite from a Cape cobra is life threatening and is a medical emergency (it is responsible for the majority of snake-bite-related fatalities
in its range). It is however important to note there is an anti-venom which although required
in large amounts is very effective.
