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.
