What is the Most Venomous Spider in the World

Spiders are one of the most feared creatures on the planet. Many dislike them and many will admit that spiders give them the creeps. A spider is an eight legged creature that belongs to the arachnid family. It has two poison fangs, two feelers, and usually two silk-spinning organs at the back end of the body. They are found on every continent in the world except for Antarctica and can be found in nearly every habitat imaginable except for the air and the sea. There are approximately 400,000 species of spider the world over. Some are harmless and some are highly venomous. So what is the most venomous spider in the world?

The world’s most venomous spider is the Brazilian wandering spider or the Banana Spider. This spider is rated as having the most active neurotoxic venom of all spiders. Research has shown that its venom is so toxic that only a tiny 0.006mg (0.00000021oz) is needed to kill a mouse. This spider was declared the most venomous spider by the 2010 Guinness World Records book. The Brazilian wandering spider is highly aggressive and found in tropical South and Central America. It is also called the banana spider has it of often found hiding in the foliage of the banana tree and in crates containing bananas. It is a wandering spider so it does not build and live in a web, but wanders the jungle floor looking for prey. Brazilian wandering spiders can grow to have a body length of 17 to 48 mm (0.7–1.9 in) and a leg span of 13–15 cm (4–5 in). They have an unusual defensive display and will lift their body into an upright position with the two front legs off the ground. In this position they sway from side to side revealing the black-striped pattern on their underside.

Most Deadly
Whilst the Brazilian Wandering spider is the most venomous spider in the world that does not make it the most deadly. That honor belongs to the Redback Spider found in Australia. The Redback spider has caused several reported deaths; however, no more deaths have been reported since the development of an anti-venom. Over 250 bites receive anti-venom treatment each year with many more cases most likely go unreported.
