5 Most Deadly Spiders on Earth



Spiders make an incalculable contribution to the Earth's ecosystem.
They clear out dangerous insect populations, preserving vital plants
and protecting animals. Their silk is a natural marvel, and merits study
for military and industrial applications to this day. Spiders are unique and
wonderful creatures, surely deserving of their place on this planet.

However, these are all things you won't be thinking the moment you see
one of these bad boys crawling up your leg. Below are the five deadliest
spiders known to man.

1. The Redback



The first deadly spider in the list is the Redback Spider found throughout
Australia. The female Redbacks are usually black in color with traces of
red and orange stripes on (you guessed it) its back. These spiders have
neurotoxic venom and their bite may cause muscle weakening, nausea,
vomiting and sweating.


2. The Funnel-Web



The Funnel-Web Spider also originates from Australia. The male funnel
web spiders are the real killers and are colored black or brown with a
glossy finish. These spiders, while attacking, stand up to their hind legs,
exposing their fangs. They also possess neurotoxic venom and their bite
may cause sweating, muscle jerking, salivation, and tears. Tears may
also be caused by looking at them!

3. The Brazilian Wandering



Brazilian Wandering Spiders are found in South American jungles. They
are nervous and aggressive by nature and produce toxic venoms as well.
Its bite is apparently particularly painful because it releases serotonin into
your bloodsteam.

4. The Brown Recluse



This is a small spider with its back in the shape of a violin just at the back
of its head. The venom of Brown Recluse Spiders causes ulcers. While its
bite is not painful, its venom causes the afflicted flesh to rot and fall away.
Yikes!

5. The Black Widow



The black widow spider is perhaps the deadliest. These glossy black
spiders can be found in North America. The neurotoxic venom they
release causes a lot of pain when it bites, with two fang marks clearly
visible afterwards. The symptoms of its bite include abdominal and back
pain, abdominal muscle cramps, delayed breathing, high blood pressure,
restlessness, and, in some cases, death.
