|Common Names:||Black Spitting Cobra, Equatorial Spitting Cobra|
The Black Spitting Cobra has a robust body with a large head slightly distinct from the neck. It has a stretchable fold of skin on both sides of the neck, which forms a hood, is unpatterned. The dorsal surface is uniformly iridescent black, while the ventral side is bluish-grey with white blotches on the throat and neck. It can grow to a total length of up to 1.5 m.
The species ranges from southern Peninsular Thailand, Peninsular Malaysia, Sumatra, the Riau Archipelago to Borneo, Palawan and the Calamianes Archipelago in the south-eastern Phillippines.
In Singapore, this species is found throughout Singapore.
The Black Spitting Cobra is mainly diurnal and terrestrial. It inhabits forest, scrubland, and gardens. It is highly venomous and when provoked, it will raise the front part of itsbody, extend its hood and hiss loudly. It may also eject fine sprays of venom from its fangs, targeted at the eyes of the provoker. The spray can cover a distance of more than one metre, causing discomfort to the provoker and even temporary blindness, should venom enter the eyes. If bitten, the venom affects the nervous system and could potentially be fatal. This species is usually not aggressive if left alone.
It feeds on small animals, such as rats and toads.
Oviparous; clutches contain 6–23 eggs.
