Few animals strike as much fear into people as venomous snakes.

Th...
The “black,” or black-mouthed, mamba (Dendroaspis polylepis) inhabits rocky savanna and can often be encountered on the ground, where it seems to be fond of termite mounds. Ranging in color from gray to dark brown, its name derives from the blackened inside of its mouth. The black mamba is feared because it is large and quick, and it possesses an e...
The venom of some species, including the Okinawa habu (T. flavoviridis), an aggressive snake that often enters human dwellings in the Ryukyu Islands, is mildly dangerous. On the other hand, the venom of the terciopelo (B. asper), the fer-de-lance of Central America is necrotizing, painful, and often deadly. Other dangerous fer-de-lances include the...
The boomslang (Dispholidus typus) hunts by extending the forward part of its body motionless from a tree, its form mimicking a branch. A rear-fanged snake, it delivers its venom by chewing on its victim until the victim succumbs to the toxins.
The eastern tiger snake (Notechis scutatus) is the most widely distributed type of tiger snake, which inhabits the southern fringe of Australia and the region’s nearby islands. As it prepares to strike, it flattens its head and neck in a manner similar to Asian and African cobras.
The saw-scaled viper (Echis carinatus) may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined. 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 banded krait (Bungarus fasciatus) is a highly venomous relative of the cobra. Its venom is essentially a neurotoxin that induces paralysis.
The king cobra (Ophiophagus hannah) is the longest venomous snake in the world. Its bite delivers a tremendous amount of paralysis-inducing neurotoxins. 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 bite of an inland or western taipan—Oxyuranus microlepidotus, also called, appropriately, the fierce snake—delivers a veritable witch’s brew of toxins. 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 mu...

Many of the world’s most venomous snakes live in tropical regions, but some live in oceanic waters. There may even be some living in captivity. The potency of a snake’s venom can be quantified by its LD50. This is the median lethal dose or concentration required to kill half of a test population.
