There are two fully operative canaliculate fangs on each side. These are shed singly at intervals. The fangs are about 7 mm in length. The poison glands are similar to the parotid salivary glands in mammals and have the shape and size of an almond kernel. Indian cobras are oviparous and lay their eggs between the months of April and July.

Venom of Indian Cobra
The venom is a clear, viscid fluid resembling olive oil in appearance. The amount of venom secreted varies with age, vitality and temper of the animal. The poison acts mainly as a neurotoxin and blood and cell destroyer. The neurotoxin paralyses the respiratory centre and is the chief cause of death. Other deadly effects of the venom are loss of clotting power of the blood and destruction of red blood cells.

The symptoms are a stinging or burning plan accompanied by swelling and oozing of bloodstained serum. The effects are gradual but rapidly advancing paralysis commences with the legs, the neck droops, the muscles of the tongue, lips, and throat, are affected and speech becomes difficult. The lower lip falls and allows saliva to dribble, swallowing becomes difficult or impossible. Breathing becomes difficult, laborious and stops. Other symptoms are vomiting and haemorrhage from the various orifices of the body.

The bite of a cobra is not fatal at all times. Fatality depends on the quantity of venom injected, the natural resistance of the victim, the condition of the snake and various other factors.
