Top 10 Scariest Spiders

Be careful before walking in the Amazon rainforest in Brazil. You might see these large spiders in the forest. Unfortunately, they are very deadly resulting in a powerful bite. If left untreated, the venom will kill a adult human. The venom will automatically kill a mouse. It is the No. 1 deadly spider in the world.

This is a spider to be scared of. It is highly aggressive and super poisonous. In fact, in 2010, the Guinness Book of World Records named it the deadliest spider in the world.

I hate spiders, all spiders. But according to information in comments, it seems this is the most deadly spider!

Ah yes, the Brazilian Wandering Spider, also known as NOPE. I hate spiders and this will kill you. No thank you.

These spiders are black with a red hourglass printed on it's back. If accidentally touched or sat on, they will bite. The bite is 15 times more powerful than a rattlesnake bite. That's why you need immediate medical care. It is the No. 2 deadly spider.

Black widows are a scary spider. A black widows bite possibly can kill someone! I'm not saying the bite WILL kill someone.

Just think of the song... Think of the song... Think of the song by Iggy...

Small but creepiest

It might be large, but the wolf spider can bite, causing pain, stings, and redness to the area. Rarely, they cause powerful bites depending on the species.

Because they look very scary and are the best scariest spiders in my family but my brother and my mum and me .me and my brother don't like spiders but my mum does

The mouse spider lives in Australia. They can cause serious symptoms if touched or threatened. It's bite is powerful and threatening.

It looks quite scary but it looks like it might have a threatening and poisonous bite that might kill you if you pester it.

The Sydney Funnel Web Spider is much more defensive than the Brazilian Wandering Spider (look at the videos and tell me which one is more aggressive). With long fangs than can pierce a toenail, drip extremely toxic venom and strike repeatedly down, this is a scary spider. The SFW also rarely dry bites, meaning that each time they bite, they almost certainly inject venom. The BWS does frequently dry bite however. The SFW also has a tendency to wander into people's houses, hiding in shoes. They don't appreciate you trying to put your foot into the shoe when they are in there either. Once again, watch the videos.

Size, hairiness and habitat aside, the SFW's venom (atrotoxin) affects primates (I.e. humans) significantly more than the BWS's venom (neurotoxin). The BSW earned it's reputation primarily based on Guinness World Records LD50 measurement of how much venom is required to kill a test population of mice. We are not mice.

The facts also suggest that the SFW has killed ...more

These spiders pack a powerful bite if threatened. DON'T play or try to pick one up. The spider lives in Australia near the east coast in Sydney.

I like spiders and dear god, this is scary. Snake sized fangs, bad temper, and decent intelligence for a spider make this nightmarish.

Big as tarantulas, bite more powerful than a rattle snake.

Now we're talking! It is normal to be scared and terrified of this spider because leg spans can increase from 25 to 30cm. It is the largest spider and tarantula in the world and lives in Northern Brazil near the Amazon rainforest. However if threatened, the spider will bite but hardly cause any pain.

I have a serious fear of spiders...And I learned this one can grow as big as a dinner plate.

The Brown Recluse spider originates from the southern states. Like the black widow, if accidentally touched or sat on, it will bite, but the venom is less powerful. The spider is quite big. Often, the spider lives in the basement or behind dusty wardrobes.

First thought that entered my head: OH MY GOD... This this is freaky..

This spider has the largest leg span in the world. No wonder it is so scary! It can have spans of up to 35cm making it the largest leg spanned spider ever. Don't try to disturb it otherwise it will bite. Often the spider will give a warning before biting.

Aren't these the spiders I see on YouTube that are the size of dinner plates and jump in Austrailia?!

This is the fastest spider in the world with top speeds up to 10mph. If it bites it causes wounds and moderate bleeding causing scars lasting up to 4 weeks.

The Camel Spider is creepy and very poisonous, but it's not actually a spider. It's more of a close cousin.

Google image search this thing right now and tell me a Black Widow is scarier... I live among these beasts. They are sooo scary

Spiders are like onions. They have layers.
