The eastern green mamba (Dendroaspis angusticeps) is a highly venomous snake native to the coastal regions of southern East Africa. First described by Scottish surgeon and zoologist Andrew Smith in 1849, the mamba has a slender build with bright green upperparts and yellow-green underparts. The adult female averages around 2.0 m in length, and the male is slightly smaller. A shy and elusive species, it is rarely seen; its green colouration blends with its arboreal environment. It has been observed to lie in wait like many vipers instead of actively foraging. The eastern green mamba preys on birds, eggs, bats, and rodents such as mice, rats, and gerbils. Its venom consists of both neurotoxins and cardiotoxins. Symptoms in humans can include swelling of the bite site, dizziness and nausea, accompanied by difficulty breathing and swallowing, irregular heartbeat and convulsions. The most severe bites can quickly be fatal.
