green mamba or common mamba (Dendroaspis angusticeps) is a venomous arboreal snake indigenous to the eastern side of southern Africa. Eastern green mambas are the smallest members of the mamba genus, averaging 1.8 metres (5.9 feet), with known specimens to 3.7 m (12 feet). Green mambas are diurnal. Like most other snakes, the mamba avoids confrontation with humans when possible. However, continued provocation will cause the snake to strike.
green mamba's diet consists primarily of adult and juvenile birds, birds' eggs, and small mammals. Young mambas occasionally eat other reptiles, such as chameleons.
The green mamba is oviparous, laying 6-17 eggs in summer. The eggs are usually laid in a hollow tree among decaying vegetation. Hatchlings measure between 35 and 45 cm (13 to 18 inches) and are venomous from birth. Males of this species are known to engage in combat for mating rights, similar to the combat practiced by male King Cobras.
the venom contains calcicludine and dendrotoxin amongst other neurotoxins. Its venom is similar in composition and action to that of the more famous black mamba but the amount injected is relatively lower, due to the snake's smaller size. Despite this, any bite from a green mamba is potentially fatal and should be regarded as a medical emergency requiring immediate hospital treatment.
