Cape cobra
Physical features
The Cape cobra is a highly venomous, medium sized snake. It can grow up to 6 feet long.
Cape cobras have many color variations, which can range from bright yellow to almost black with varying degrees of dark stippling and blotches.
Cape cobras have a hood that is formed by expanding the ribs on the forward part of the body, just behind the head.
Cape cobras are largely terrestrial, but are also very good climbers and are often found hunting in trees.
Cape cobras are non-spitting cobras. Like other cobras, they have short fangs at the front end of the upper jaw that do not fold back against the roof of the mouth.

Reproduction
Cape cobras are oviparous and during midsummer (December-January) will lay between 8-20 eggs, depending on the size of the female. Eggs are laid in a rodent burrow, termite mound, or other moist location where they incubate for about 2-3 months.
Newly hatched cape cobras are between 12-16 inches and are completely independent.
New hatchlings have a dark band around their throat that is believed to allow them to mimic the spitting cobra. This is a defensive mechanism that gradually fades as they grow.
Conservation: Not Evaluated
Major Threats: Natural predators include meerkats, mongooses, honey badgers, and birds of prey. Some of its main predators are insensitive to Cape Cobra venom.
Conservation Efforts: This species is not endangered.
Interpretive Information
The Cape cobra secretes neurotoxin venom that paralyzes prey. This venom is the most toxic of all African cobras.
Some components of the Cape cobra’s venom have been used as a basis for human drugs that treat pain due to neural dysfunction.
Cape cobras, like other cobras, are very fast-moving and active.
