|Western Green Mamba|
AppearanceSmaller than the black mamba, but larger than the eastern green mamba and the Jameson's mamba the western green mamba is a long and very slender bodied snake with a long tapering tail. It is the largest of the arboreal mambas. The average length of an adult snake of this species is between 1.8 metres (5.9 ft) and 2.2 metres (7.2 ft). Most are around 1.8 metres (5.9 ft), but specimens measuring around 2 metres (6.6 ft) are quite common also. Some specimens of this species can grow to maximum lengths of 3.2 metres (10 ft), making this species along with the forest cobra tied as the second longest venomous snakes in Africa.
The western green mamba's natural prey consists mainly of birds and small mammals, including rodents such as mice, rats, and squirrels. Other mammals include bats, tree pangolins, and shrews. They also feed on lizards, frogs, and bird eggs. This snake actively pursues its prey, striking rapidly and often until the prey succumbs to the venom.
