forest cobra
The forest cobra (''Naja melanoleuca''), also called the black cobra and black and white-lipped cobra,〔 is an elapid native to Africa, mostly the central and western parts of the continent.〔 It is the largest true cobra species with a length up to 3.1 meters.〔 Although it prefers lowland forest and moist savanna habitats, this cobra is highly adaptable and can be found in drier climates within its geographical range. It is a very capable swimmer and is often considered to be semi-aquatic.〔 The forest cobra is a generalist in its feeding habits, having a highly varied diet: anything from large insects to small mammals and other reptiles.〔 This species is alert, nervous and is considered to be a very dangerous snake.〔〔 When cornered or molested, it will assume the typical cobra warning posture by raising its fore body off the ground, spreading a narrow hood and hissing loudly. Bites to humans are less common than for other African cobras due to various factors, though a bite from this species is a life-threatening emergency.〔
==Etymology==
The forest cobra is classified under the genus ''Naja'' of the family Elapidae. ''Naja melanoleuca'' was first described by American herpetologist Edward Hallowell in 1857.〔 The generic name ''Naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The specific epithet ''melanoleuca'' is Ancient Greek and means "of black and white". The word ''melano'' is Greek for "black",〔(【引用サイトリンク】url=http://www.merriam-webster.com/medical/melano )〕 while ''leuca'' comes from the Ancient Greek word for "white".〔(【引用サイトリンク】url=http://www.merriam-webster.com/medical/leuc- )〕 This species is also known as the ''black cobra'' and ''black and white-lipped cobra''.
