Eastern green mamba (Dendroaspis angusticeps) is a deadly venomous snake living in Africa. Other green arboreal snakes are often confused for green mambas. Green snakes from the genus Philothamnus are one of them. In this video you will see the Southeastern green snake (Philothamnus hoplogaster) and Speckled green snake (Philothamnus punctatus). Highly venomous Boomslang (Dispholidus typus) can be also confused for Eastern green mamba. In this video we demonstrate that it is possible to recognize the Eastern green mamba from other green arboreal snakes of Africa.
