subject: The 5 Deadliest Spiders In The World [print this page] One of the universal fears of humans is the fear of spiders. There is good reason that humans have developed this fear. There are quite a few dangerous spiders around the world out of the over 7,000 species. While almost every single spider contains some sort of venom, most of them do not have the capability of piercing human skin and injecting this venom into people. There are also wide varieties of species that contain venom that is not considered medically significant to humans.
The spiders mentioned here do not fit into either of the aforementioned categories. These spiders contain venom that is dangerous to humans and have fangs that are able to pierce the skin of humans. If a person is bitten by one of these spiders, the advice is to seek immediate medical attention.
Black Widow This is probably the most famous of all the deadly spiders in the world. This spider has been turned into pop-culture references in comic books, bands, and other mediums. The female black widow does inject venom that is harmful to humans upon biting them. However, this bite rarely results in death due to proper medical attention and the familiarity with the species. The males venom is less strong than the female by 3 fold, which renders the male venom not dangerous to humans. Variations of the widow species are found throughout the world. Many of the species are found in warm locations like Florida, Mexico, and regions of South America.
Brown Recluse The brown recluse is another well-known venomous spider that makes it home in the United States. These spiders are found mainly in the Midwest and South and can be dangerous, especially in small children or the elderly. When left unattended, a brown recluse bite will turn into a large ulcer on the skin. These ulcers can be extremely painful and deep, taking a long time to heal and leaving scars.
Funnel-Web Spiders The funnel-web spider is predominately found in Australia, particularly in the Sydney region. These spiders have some of the most fast-acting venom of all dangerous spiders. Symptoms from a bite can start to appear in as little as 10 minutes. The most dangerous symptoms can be difficulty breathing and a coma. While there have been no deaths since the invention of modern first aid, these spiders have significantly dangerous venom.
Brazilian Wandering Spider This species of spider are also known as the Banana Spider and are known as the most venomous spider. These spiders are native to many areas in South America. While their venom contains a powerful neurotoxin, they have would have to inject enough to harm a human, which is not always the case. Spiders mouths are a result of adaptation to their prey and therefore are not as effective against humans.
Mouse Spider The mouse spider contains venom similar to the funnel-web spider. These spiders are mostly found in Australia. There have also been related species found in Chile. The mouse spiders venom has the same effects as a funnel-web spider but is less aggressive towards humans.
Almost all spiders contain some type of venom, which is how they attack their prey. Most of these spiders cannot pierce the skin of a human or their venom is not significant enough to be a danger. However, there are definitely a fair amount of species that human should be on the lookout for. Whenever you are visiting a new country, make sure to check into what type of dangerous creatures may be lurking around.
