Poisonous spiders and their different species
Spiders, we find them everywhere in every possible corner which is
untouched. Have we ever realized are these all spiders the same? Yes,
they do all look the same but, there are 38000 species of spiders spread
across over more than 100 families. They are categorized in 2 different
types like most of them are harmless, but at the same time there are
certain amounts which are poisonous.
These poisonous spiders on biting causes symptoms like nausea,
itching, stinging pain, redness swelling and if increased at a certain
level, they may also cause death. Some of them also damage our nervous
system. We normally take it very lightly of the presence of even 1
spider in our house. But, we have never known whether it is the normal
or the poisonous one as it is difficult to distinguish between the both.

Spiders are arachnids and not insects. They have fangs with which they
inject venom when they bite their victim. The most commonly known
poisonous spider is the Black Widow and they are the spiders that
account for the most poisonous spider bites in the United States and
Canada. The female of the variety is the poisonous one. They rarely
attack people but bite only when they are disturbed and feel threatened.
They are found in the high corners of the walls, clothing, unused items
and shoes. Some of them are too small to inject their venom into the
skin and even those that can, may not have venom strong enough to cause
you any damage. While experts are divided on the need to capture a
spider that has bitten you, the chances on your being bitten again make
it a hazardous task.
Some of the known Poisonous spiders are Black Widow spider, Red back
spider, Brown Recluse spider, Brazilian Wandering spider and Australian
Funnel-web spider.
The Black Widow spider has deprived its name from the belief that the
female eats the male after mating. The female have a black shiny body
with orange spots on the abdomen. The male in contrast is smaller and
not poisonous. The Black Widow spider bite can cause serious symptoms in
adults and can be fatal for children and elderly. The Red back spider
which is known as the Australian cousin of the Black widow spider is
very poisonous. They are also known as Jockey spider or Kapara spider.
The bite of these spiders causes Latrodectism. The victim experiences
hammering pain, headache, profuse sweating and burning sensation. There
are also some cases where the victim may have a respiratory problem and
they might get into coma.
The next species is Brown Recluse spider, who is found in the
mid-western region of United States and the Gulf of Mexico. They are
unique type as they are gifted with 3 eyes and resemble to of a violin.
Thus, they are also known as a fiddle-back spider.

The Brazilian Wandering spider has spun its way up to the Guinness Book
of World Records in 2007 for causing the highest number of death of
human with its venomous bite. It gets its name because during the night
it wanders around in the jungle and during the day it hides inside
termite mounds, under logs and in Banana plants. It is also called the
Banana spider. They are very aggressive and are least hesitant to bite
humans even in the absence of a threat. Its fatal venom contains PhTx3
neurotoxin which leads to difficulty in respiration, affects muscle
control and also causes paralysis or asphyxiation.
There are many other such spiders with different unique
characteristics. The best way of injecting these medicines is through
insulin needles and making sure that all the affected area of the bite
from the poisonous spider is treated. Antibiotics are also recommended
if the spider bite causes lesion and an open wound. Usually there is no
need to worry about these spiders, but just to be careful and take
precautions while dusting them off. |
