The King Cobra Snake (Ophiophagus hannah) is the largest venomous snake in the world. The King Cobra snake is also perhaps the most dangerous snake in the world where humans are concerned. Under conditions of high prey availability, they can reach a length of 18.5 feet. Several people die from the bite of the King Cobra each year. A King Cobra can even kill an elephant.
Their venom is not the most potent among venomous snakes, but the amount of neurotoxin they can deliver in a single bite—up to two-tenths of a fluid ounce—is enough to kill 20 people or even an elephant. King cobra venom affects the respiratory centers in the brain, causing respiratory arrest and cardiac failure.
Habit and Behavior:
King cobras live mainly in the rain forests and plains of India, southern China, and Southeast Asia, and their coloring can vary greatly from region to region. They are comfortable in a variety of habitats, including forests, bamboo thickets, mangrove swamps, high-altitude grasslands, and rivers.
This species feeds mainly on other snakes, venomous and nonvenomous. They will also eat lizards, eggs, and small mammals. They are the only snakes in the world that build nests for their eggs, which they guard ferociously until the hatchlings emerge.
The Black mambas are fast, nervous, lethally venomous, and when threatened, highly aggressive. They have been blamed for numerous human deaths, and African myths exaggerate their capabilities to legendary proportions. For these reasons, the black mamba is widely considered the world’s deadliest snake.
Black mambas live in the savannas and rocky hills of southern and eastern Africa. They are Africa’s longest venomous snake, reaching up to 14 feet in length, although 8.2 feet is more than the average. They are also among the fastest snakes in the world, slithering at speeds of up to 12.5 miles per hour.
Before the advent of black mamba antivenin, a bite from this fearsome serpent was almost always fatal, usually within about 20 minutes. Unfortunately, antivenin is still not widely available in the rural parts of the mamba’s range, and mamba-related deaths remain frequent.
Encroachment on the black mamba’s territory is not only putting pressure on the species but contributes to more potentially dangerous human contact with these snakes.
Habit and Behavior:
They get their name not from their skin color, which tends to be olive to gray, but rather from the blue-black color of the inside of their mouth, which they display when threatened.
Black mambas are shy and will almost always seek to escape when confronted. However, when cornered, these snakes will raise their heads, sometimes with a third of their body off the ground, spread their cobra-like neck-flap, open their black mouths, and hiss. If an attacker persists, the mamba will strike not once, but repeatedly, injecting large amounts of potent neuro- and cardiotoxin with each strike.
