The African forest cobra contains neurotoxins that could help treat Alzheimer's disease. After catching this forest cobra in a friend's attic, Donald takes it outside to extract its venom.
On Animal Planet's series "Fooled by Nature," When attacked the cobra spits venom up to 8 feet in order to blind the enemy. It's venom is a neurotoxin which can produce pain and blindness.
Is the megaconda real? The evidence is spotty, but some say this monster-snake exists, reaching lengths in excess of 130 feet and weighing as much as 5 tons.
