8 of the World's Deadliest Snakes


Few animals strike as much fear into people as venomous snakes. Although the chances of running into a venomous snake, much less being bitten and dying from the toxin injected into one's body, are miniscule compared to dying from cancer, heart disease, or an automobile accident, this seemingly unreasonable fear remains very real for many people. The snakes described here live primarily in tropical regions, but some might be living in research centers and zoos near you.

Some officials maintain that young fer-de-lances may be more deadly than the adults because they have not learned to control the doses of venom they deliver.

A rear-fanged snake, it delivers its venom by chewing on its victim until the victim succumbs to the toxins.

As it prepares to strike, it flattens its head and neck in a manner similar to Asian and African cobras.

The killer of the most people

Its venom, however, is lethal in less than 10 percent of untreated victims, but the snake's aggressiveness means it bites early and often.

The snake's venom is so strong and so voluminous that it can kill an elephant in just a few hours. Death also results in at least 50 to 60 percent of untreated human cases.

The coastal taipan (Oxyuranus scutellatus) produces venom that is nearly identical to that of its inland cousin. Its bite is lethal in more than 80 percent of untreated cases.

The venom consists of taipoxin, a complex mix of neurotoxins, procoagulants, and myotoxins that paralyze muscles, inhibit breathing, cause hemorraging in blood vessels and tissues, and damage muscles.
