The forest cobras are snakes that are well adapted to many environments and the habitat of the forest cobra is strongly dependent on what part of its African range the snake originates from. Forest cobras originating in the southern African regions are typically found in savanna and grassland, but they can also be found in broken rock country.
The two species of black desert cobras or desert black snakes, Walterinnesia aegyptia and Walterinnesia morgani, neither of which rears upwards and produces a hood when threatened [4]: p.65 The eastern coral snake or American cobra ( Micrurus fulvius ), which also does not rear upwards and produce a hood when threatened [ 4 ] : p.30
It is a quick-moving and alert species, [8] and although a report mentions that this species is generally calm when compared to some other African venomous snakes, [7] it strikes readily if threatened. When disturbed and brought to bay, the Cape cobra raises its forebody off the ground, spreads a broad hood, and may hiss loudly.

The Chinese cobra is a highly venomous member of the true cobras (genus Naja). [14] The murine LD 50 values of its venom are 0.29 mg/kg IV [15] and 0.53 mg/kg [5] —0.67 mg/kg SC. [15] The average venom yield from a snake of this species kept at a snake farm was about 250.8 mg (80 mg dry weight).
Just like most snakes in the Elapid clade, spitting cobras inject their venom through a bite in order to kill their prey. Spitting was evolved as a defense mechanism to deter predators; even if a Spitting cobra blinds a threat, that is not enough to kill the attacker and therefore spitting cobras can also inject venom directly.
Snake charmers with their cobras in a wicker basket are a common sight in many parts of India only during the Nag Panchami or Naagula Chavithi festival.

In Ptolemaic Egypt, the term "aspis" (an ancient Greek word referring to a wide variety of venomous snakes) was most likely an Egyptian cobra. This aspect of her apparent suicide has been questioned in recent years, as the relatively large size of the snake would have made it difficult to conceal, and because Egyptian cobra venom is slow-acting ...
