Eastern Green Mambas

Genus: Dendroaspis

The eastern green mamba is a species of snake commonly found throughout East Africa, and occasionally in Southern Africa. It is closely related to the black mamba and, like the black mamba, is highly venomous. There are four types of mambas in the wild; the Jameson’s mamba lives in central Africa; the western green mamba exists in West Africa and the infamous black mamba dwells in Sub Sahara Africa.

The name of name of the eastern green mamba derives from its coloring: adult snakes have bright green scales on their tops, and belly scales are made up of light, yellow-green scales. They are characterized not only by their long bright bodies but also viewed on a side angle, they appear to be smiling. Plus, like the black mamba, the Green Mamba has an ominous coffin shaped head which is distinctive from the shape of the rest of the snake. Very young eastern green mambas might have slightly blue-green scales. Good eyesight allows them to target fast prey with their poisonous bite.

Female eastern green mambas can grow to around 2 meters, (6 to 7 feet in length) while males are slightly shorter at 1.8 meters (occasionally 8 to 8½ feet) . They are diurnal, so they are awake during the day and sleep at night. They are also solitary creatures, with most snakes living on their own. This only changes slightly during the mating season.

Habitat of the Eastern Green Mamba

This is good for them, since they are an arboreal species, meaning they live and hunt primarily in the trees. Eastern green mambas are shy and elusive snakes. They prefer to avoid humans, and since they blend in so easily, they are often successful. These luminous like snakes are most often seen during their mating season, as they are more active then.

These snakes live almost entirely in trees. While they can be seen on the ground, they prefer to stay in the trees whenever possible. Because of this, they are usually only found in highly forested regions, and stay away from open plains or other open areas and hardly venture further than 7km inland.

The eastern green mamba snake only lives in the wild in KwaZulu-Natal and the furthest northeastern part of the Eastern Cape at Kosi Bay in South Africa but its full territory extends southernly from Kenya, through Tanzania, Malawi, and the east of Zimbabwe.

Unlike many other snakes, which will often hunt for their food, eastern green mambas usually prefer to use the sit-and-wait, or ambush, method. They will find a spot where they are camouflaged, and rest there, sometimes for hours. Then, when suitable prey passes by, they will quickly strike. They feed on birds, bird eggs, bats, and sometimes arboreal lizards. They can also eat many species of rodents, like mice, rats, gerbils and squirrels.

In more severe cases, it can cause necrosis, gangrene, paralysis, and respiratory failure.
