According to the Guinness Book of records, 2010, the world’s most venomous and therefore most dangerous spider is the Brazilian wandering spider which produces enough venom to kill two people at a go. Have you seen these deadly spiders? Watch out for it in Banana plantations.
While most spiders are harmless and won’t even bite, there are those that are dangerous and can easily cause death. Which one is the world’s most dangerous spider? Which spider is the deadliest of them all? Research reveals that the most poisonous spider and therefore the most dangerous is The Brazilian Wandering Spider also known as the Banana Spider.
These spiders are highly aggressive and venomous. They are widely distributed in forests in Central and South America, particularly Costa Rica, Argentina, Colombia, Venezuela, Peru, Bolivia, Brazil and Paraguay. They are large spiders that have a body size of up to 4.8 cm with a leg span of more than 15cm.
There venom contains a powerful neurotoxin called Phoneutria nigriventer toxin-3 (or simply PhTx3) that acts as a calcium channel blocker and inhibits glutamate release, calcium uptake, and glutamate release at synapses. When in large concentrations, the spiders’ deadly toxin can lead to one of the following: -
- Loss of muscle control
- Breathing problems resulting in asphyxiation
- Intense pain and inflammation
- Priapism (prolonged erection)
- Paralysis and even death
Could this be the world’s most dangerous spider? Whether it is the deadliest of all or not, there is a need to watch out for it in the jungle particularly inside banana plantations.
