Cobras are also virulent with 30,000 deaths reported annually in China alone. They hang around crumbling ruins and lurk in roofs of huts. They're waiting for rodents and lizards, but if disturbed by a human they will react defensively. They strike swiftly and accurately or they spit venom several feet in front of them. The venom acts as an anesthetic so the victim feels no fear, no anxiety, no pain, almost as if hypnotized.
Rattlesnakes also have deadly venom.
The young are born live, rather than from eggs, and they are born ready to strike with venom sacks full. In fact, the bite of a young rattler may be more potent than an adult's, plus multiple bites may occur as a litter of as many as 20 emerge. Emulating the rattlesnake is the harmless gopher snake. Most predators don't take any chances and leave them alone. Snakes come in so many colors and wonderful patterns of spots, stripes and bands.
