THE WORLD'S MOST POISONOUS SNAKES
Added on: 27th Oct 2016
DUBOIS’S SEA SNAKE
This treacherous swimming snake is found from the coasts of
western and northern Australia to the islands of New Guinea
and New Caledonia. Although the Dubois’s sea snake has
one of the deadliest venoms known, its bite, thank God!,
delivers less than one-tenth of a milligram, which is
usually not enough to kill a human.
A typical ambush predator, the eyelash viper waits patiently
for unsuspecting prey to wander by. Sometimes it is known
to select a specific ambush site and return to it every
year in time for the spring migration of birds. Studies
have indicated that these snakes learn to improve their
strike accuracy over time, while there are rumours among
villagers in parts of South America that this snake will wink,
flashing its eyelashes at its victim, following a venomous strike.
Many venomous members of the family Colubridae, to which the
boomslang belongs, are harmless to humans because of
small venom glands and inefficient fangs. However, the
boomslang is a notable exception in that it has a highly potent
venom, which it delivers through large fangs located at the back
of its jaw. Boomslangs are able to open their jaws up to 170°
when biting, releasing bigger amounts of venom, which usually kills
the victim from internal or even external bleeding.
A bite from the notoriously venomous eastern coral snake
at first seems anticlimactic. There is little or no pain or
swelling, and other symptoms can be delayed for twelve hours.
However, if untreated by antivenin, the neurotoxin begins to
disrupt the connections between the brain and the muscles,
causing slurred speech, double vision, and muscular paralysis,
eventually ending in respiratory or cardiac failure.
GWARDAR OR WESTERN BROWN SNAKE
The western brown snake, or gwardar, is a species of very fast,
highly venomous elapid snake native to Australia. Its colour
and pattern are rather variable, depending largely on its
location, but its venom and the fatal damage it causes its
victims (including humans) is standard.
Saw-scaled vipers are small but their irritability, aggressive
nature, and lethal venom make them very dangerous. They
are usually quick to strike and mortality rates for those
bitten are high. In the regions where they live (Africa, Arabia,
Southwest Asia), it is believed that saw-scaled vipers are
responsible for more human deaths than all other
snake species combined.
Even though rattlesnake bites are rarely fatal to humans when
given proper medical treatment (including antivenin), its
bites are some of the most frequent among all snakes.
The greatest concentration of them is in the Southwest and
northern Mexico, while Arizona is home to thirteen
species of rattler, more than any other state.
Arguably the most popular snake in the world, this highly
venomous snake feeds on rodents, lizards and frogs. As well
as biting, the Indian cobra can attack or defend itself from
a distance by “spitting” venom, which, if it enters the
opponent’s eyes, causes severe pain and damage.
