Black Mamba vs Green Mamba: 5 Key Differences

While a black mamba vs green mamba are both extremely venomous snakes, there are many key differences between them. But how can you tell these two snakes apart, especially if you aren’t sure what their differences are? Not only do these two snakes belong to the same family or species, they live in similar areas as well.

In this article, we will address all of the differences between a black mamba vs green mamba, including their appearances and preferred diets. You may be surprised by how different black mambas and green mambas actually are! Let’s get started and learn more about these misunderstood snakes now.

Comparing Black Mamba vs Green Mamba

Key Differences Between Black Mamba vs Green Mamba

There are many key differences between a black mamba and a green mamba. The appearance of a black mamba differs in both size and color from a green mamba. You will also find green mambas in wet forests, while black mambas prefer grasslands and more arid climates. Finally, black mambas take down far larger prey when compared to the dietary preferences of green mambas.

Let’s talk about these differences in more detail now.

Black Mamba vs Green Mamba: Size and Weight

There are some vast size and weight differences between the black mamba and the green mamba. For example, the black mamba reaches anywhere from 6-12 feet long if not longer, and green mambas average anywhere from 4-7 feet in length. There have even been some black mambas recorded up to 14 feet long, while green mambas never grow so large.

The body styles of these snakes also differ slightly, though you may not be able to tell unless you are looking at them side by side. However, as a rule, green mambas have a more slender body compared to the body of a black mamba.

Black Mamba vs Green Mamba: Location and Habitat Preferences

You may find black mambas and green mambas in similar locations, but this does not mean they enjoy the same habitats as one another. While both of these snakes are found in Africa, black mambas are found in Central Africa and along the eastern coastlines, while green mambas live along the western and eastern coastlines almost exclusively.

Black mambas enjoy arid grasslands and hotter climates just as well as wet rainforests, while green mambas live exclusively in damp and coastal forests. Given the exclusivity of the green mamba’s preferred habitat, they often encroach upon populated areas, while black mambas prefer to avoid humans at all costs.

Black Mamba vs Green Mamba: Appearance

Not only are there size and weight differences between a black mamba and a green mamba- their physical differences continue. Green mambas live up to their namesake and come in shades of green, yellow, and turquoise, while black mambas come in shades of gray, brown, and cream. 

While it may surprise you, black mambas are rarely black- they are called black mambas because the insides of their mouths are black, while green mambas have pink mouths. The head shape of these snakes is similar, except a black mamba has a hood like that of a cobra, while green mambas do not share this.

Both of these extremely venomous snakes have round pupils, which is interesting to note. Many venomous snake species have vertical slits for their pupils, and many non venomous snakes have round pupils. However, this is not the case for the exceedingly venomous black and green mambas.

Black Mamba vs Green Mamba: Behavior

While both black mambas and green mambas prefer to be left alone rather than engage in aggression, there are some behavioral differences between them. For example, green mambas often live in populated areas, while black mambas do their best to avoid people at all costs. Black mambas have a particularly bad reputation, even more so than green mambas.

Another behavioral difference between these two snakes is that black mambas are capable of rising to tall heights when threatened, while green mambas are not. Black mambas also use their small hoods to appear larger, behaving in a similar fashion to cobras. Green mambas run away from any threats, often escaping at speeds exceeding 7 miles per hour!

Black Mamba vs Green Mamba: Diet and Hunting Style

Black mambas and green mambas have different diets, especially when you consider their geographical locations. Black mambas eat bush babies, hyraxes, birds and their young, mammals, and other snakes, while green mambas eat birds, their eggs, small bats, and lizards.

Green mambas spend the majority of their time in trees and branches, which is why birds and bird eggs are their primary source of food. Black mambas spend comparatively more time on the ground, and can take down larger prey than green mambas can.
