From today's featured articleJameson's mamba (Dendroaspis jamesoni) is a species of highly venomous snake native to equatorial Africa. A member of the mamba genus Dendroaspis, it is slender with dull green upperparts and cream underparts and generally ranges from 1.5 to 2.2 m (4 ft 11 in to 7 ft 3 in) in length. Described by Scottish naturalist Thomas Traill in 1843, it has two recognised subspecies: the nominate subspecies from central and western sub-Saharan Africa and the eastern black-tailed subspecies from eastern sub-Saharan Africa. Predominantly arboreal, it preys mainly on birds and mammals. Its venom consists of both neurotoxins and cardiotoxins. Symptoms of envenomation in humans include pain and swelling of the bite site, followed by swelling, chills, sweating, abdominal pain and vomiting, with subsequent slurred speech, difficulty breathing and paralysis. Fatalities have been recorded within three to four hours of being bitten. The eastern subspecies is twice as venomous as the nominate subspecies. (Full article...)
