Which snake venom is neurotoxic?
Cobra venom (cobratoxin) is a small basic protein (Mr = 7000). It contains 62 amino acids in a single chain, cross-linked by four disulfide bonds. The toxin comprises 10% of the venom by weight. It is a neurotoxin that is secreted by glands of the cobra snake and injected into its prey via immobile, grooved fangs.

What venom does to blood?
It can trigger lots of tiny blood clots and then when the venom punches holes in blood vessels causing them to leak, there is nothing left to stem the flow and the patient bleeds to death.
