Cobras, mambas, and taipans are mid- to large sized snakes which can reach 2 m (6 ft 7 in) or above. The king cobra is the world's longest venomous snake with a maximum length of 5.85 m (19.2 ft) and an average mass of 6 kg (13 lb). [7]
The black mamba's mouth is black within, which renders the threat more conspicuous. A rearing mamba has a narrower yet longer hood and tends to lean well forward, instead of standing erect as a cobra does. Stories of black mambas that chase and attack humans are common, but in fact the snakes generally avoid contact with humans. [5]

The black-banded sea krait (Laticauda semifasciata), also known commonly as the Chinese sea snake or erabu, is a largely amphibious species of venomous marine reptile in the subfamily Laticaudinae, family Elapidae (cobras, mambas, coralsnakes and their kin). It is found in much of the western Pacific Ocean and some of the Sea of Japan.
Spitting cobras belong to the Elapidae, which comprises snakes including cobras, mambas, coral snakes, kraits, taipans, death adders and sea snakes. [2] Many snakes use their venom as both a defensive and predatory mechanism, and this includes the spitting cobras.
The proteins in black mamba venom are of low molecular weight, low viscosity, and the venom's high activity in terms of hyaluronidases, which is also essential in facilitating dispersion of venom toxins throughout tissue (spreading the venom through the body) by catalyzing the hydrolysis of hyaluronan, a constituent of the extracellular matrix ...
The cobra's diet mainly consists of amphibians, other snakes, birds, eggs, small mammals, and occasionally even insects. [4] This cobra has been reported to scavenge and eat carcasses in an advanced stage of decomposition. [7] It has been documented feeding on venomous snakes such as black mamba and has developed immunity to its venom. [8]
