2. SYDNEY FUNNEL -WEB SPIDERSydney Funnel-web spider usually found within 100-150 kilometres around Sydney, Australia, is as much aggressive and venomous as the Brazilian Wandering Spider and a single bite from this spider can also be lethal! It is medium to large in size, with a body length ranging from 1 to 5 cm (0.4 to 2 in).
The rare distinction among these and other spider species is that males are more deadly and have very sharp fangs (which is not common among spiders) and are more likely to pounce and attack an enemy whereas the female spiders are comparatively less toxic. Being the most venomous spider in Australia, its venom is twice as strong as cyanide!

They can also be seen in the west to the Blue Mountains in New South Wales and moist microhabitats that includes under logs and foliage.
3. BLACK WIDOW SPIDER
The prevalence of sexual cannibalism, a behaviour in which the female eats the male after mating, has inspired the common name “widow spiders”. Though it looks considerably small, it proves that appearances can be deceptive, inflicting a severe bite. Its venom is 15 times stronger than a rattlesnake’s! A single bite can cause extreme sweating, muscle aches, severe pain in the abdomen, hypertension and paralysis of the diaphragm. A lot of pain…all at once, sounds pretty scary, right?

4. GIANT HUNTSMAN SPIDER
This is the kind of spider which gives you the creeps. Huntsman Spiders, usually found in Australia, New Zealand, Southeast Asia, the Mediterranean, Florida and Hawaii and possibly in many other tropical and semi-tropical region has eight scary eyes and by leg span, the Giant Huntsman is considered the largest spider around just barely beating the Goliath Birdeater Spider (which also makes our top ten list).It has a huge 30 centimetre (12 in) leg span and around 5-centimetre body length (2 in). Its venom is not deadly and it is timid and does not really attack humans but by the bare sight of the spider, you will want to get as far away from it as possible.

Koch, 1875) with a body length of about 4 centimetres.
5. BROWN RECLUSE SPIDER
These spiders are well known for their appearance and their poisonous bite and are distinguished from the others by the fact that they have six eyes arranged in three pairs. It is the most common and widespread of the brown spiders-which is even scarier because at a single glance, humans cannot distinguish between normal spiders and the Brown Recluse and unlike normal spiders, if bitten immediate medical attention is required without which it causes severe damage and also prove to be fatal- but it is found only in the south and the central United States.

The markings on the dorsal side of their cephalothorax can be seen with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider and hence called by different names such as fiddleback spider, brown fiddler, or violin spider.
6. GOLIATH BIRD-EATER
Despite their name, it is uncommon for these species to eat birds and their appetite is usually based on insects, worms and other spiders. The Goliath Bird-Eater Spider is actually one that belongs to the Tarantula group and it is the world’s biggest tarantula and the heaviest spider weighing around a massive 170-200g!

Also, the species is harmless to humans and only time when they attack humans when they are threatened. If you keep a distance from them, you will be safe.
7. ZEBRA SPIDER
Although these scariest spiders can grow up to only around 7-9mm, they pack a few scary and surprising tricks in their arsenal. These spider species have superb jumping skills and can jump up to almost 20 times their own size! This supersedes the need for them to build webs and they have 4 pairs of huge eyes to locate their prey. The name Zebra Spider is because of the black and white stripes on their back. These spiders are found almost all over the world but mainly in Europe and America. It is very agile and can react very quickly to danger. You wouldn’t want a spider jumping on you now, would you?
8. WOLF SPIDERWolf Spiders can be seen almost everywhere in the world and are especially common in grasslands and meadows according to BioKids. They are solitary, nocturnal creatures that prey during the night. They attack when threatened but their toxins are not very harmful and can be treated using the right anti-venom.
9. BIRD DUNG CRAB SPIDER

10. HOBO SPIDER
The Hobo Spider is very threatening and rapacious in nature. Mostly found in Europe and parts of Central America, it is right up there with Black Widow and the Brown Recluse spider when we consider what people generally identify them for. But, these spiders best defensive mechanism is to hide and avoid any combat but it does have mild toxic venom which these days, can be cured. These species are widely considered as scary because of the reputation it gets from its appearance alone.
The world’s largest spider is the size of a dinner plate
Most spiders are only a few centimetres long, but a few species have grown far, far biggerYou might think you would notice an eight-legged animal the size of a dinner plate, but in fact many of the world’s biggest spiders are easily overlooked.
In Europe, the Desertas wolf spider is only found in a single valley on the island of Madeira, Portugal. It is one of the world’s largest wolf spiders, with a body length of up to 1.6 inches (4cm) and distinctive black legs with white polka dots.
The family name conjures up fierce and predatory associations, and rightly so. Wolf spiders are named for their active hunting style. Instead of capturing prey in a web, these arachnids pounce on their meals.
Like any self-respecting legendary spider, it lives in a cave
However there are ways in which they differ from wolves. The spiders are solitary rather than pack hunters, so they ambush their prey or chase it down over a short distance. Also, they hunt millipedes, not mammals.
The most distinguishing characteristic of wolf spiders is the layout of their eyes. They have a row of four small ones, with two larger eyes above, topped by another two slightly smaller ones that boost their predatory senses. The Desertas wolf spider’s excellent eyesight allows it to hunt fast-moving beetles and even small lizards.
A similarly remote location is home to one of Asia’s biggest spiders: the giant huntsman spider.
It has a leg span of up to 30 cm (1 foot), which has been championed as the world’s biggest. Like any self-respecting legendary spider, it lives in a cave.In 2001, Peter Jäger discovered the species in a collection at the National Museum of Natural History in Paris, France, before heading out to Laos to visit its secluded habitat. Why it grows to such a significant size remains something of a mystery.
When approached, a king baboon spider rears up to expose its fangs and hisses loudly by rubbing its legs together
«A straightforward explanation is difficult,» says Jäger, «But I guess one reason in the case of H. maxima is certainly the cave-dwelling habit… prey is scarcer than outside, [meaning] growth is slower and this may result in bigger size.»
Unfortunately the media spotlight on the giant huntsman has had negative consequences. Jäger reports that its numbers are dwindling due to unregulated demand by the pet trade.
There are also large huntsman spiders in Australia. They usually hide under loose tree bark, but their long legs have also been spotted behind wall clocks and sun-visors in cars.
Since they prey on pests such as flies, they should be considered welcome guests. But their crab-like appearance, leg span of up to 6 inches (16cm) and ability to deliver a nasty nip when provoked can be alarming.
The huntsman might have the best pins, but the true heavyweight champions are the tarantulas.
One of Africa’s largest living spiders is the king baboon tarantula. It has a leg span of up to 8 inches (20cm) and is rusty red-brown in colour. In the wild it digs into the soil of grasslands, then constructs webs across its burrows to catch prey.
Hysterocrates hercules has a name which is bigger than the actual spider!
Their size makes them popular pets, but their temperament is less appealing. Their common name refers to the fact that baboons often eat them, and as a result they are highly defensive towards primates, including humans. When approached, a king baboon spider rears up to expose its fangs and hisses loudly by rubbing its legs together.
There is another species of African tarantula revered among collectors. There is a thriving unscrupulous online trade in «super-sized» Hercules baboon spiders, even though they have not been seen in the wild since 1900.
«Hysterocrates hercules has a name which is bigger than the actual spider!» says Richard Gallon from the British Arachnological Society. «Although the only known specimen has the largest carapace of any African spider, there are other species of tarantula in Africa which are heavier and with larger leg-spans.»
The first part of the Goliath birdeater’s name is no exaggeration
That single specimen resides in a jar of preserving alcohol in the Natural History Museum in London, UK.
There are unlikely to be more anytime soon. «Hysterocrates hercules was collected from central Nigeria, an area which is now politically unstable, so not a place for researchers to risk their lives visiting,» says Gallon. «Grassland tarantulas are also difficult to find, often needing several hours of searching by an experienced team to locate specimens.»
In 2011, staff at the Natural History Museum brought in a Guinness World Records expert to witness a showdown. They measured the volume of their Hercules baboon spider against a similarly-preserved Goliath bird-eating spider. This settled the matter: H. hercules was less than a third of the size of Goliath.
The first part of the Goliath birdeater’s name is no exaggeration. Its legs span 11 inches (28cm), just shy of the giant huntsman, but it is a much bulkier animal.
Size is much debated, particularly among the tarantula breeding community. But one of the heaviest captive-bred specimens was identified by Guinness experts as Rosi. She weighed in at 6 oz (175g) and had a body length of almost 4.7 inches (12cm).
In the wild, Goliath birdeaters are rarely encountered. They live in the upland rainforests of South America and are nocturnal. To maintain their impressive physiques, they are voracious predators – of earthworms.
The B-movie moniker comes from early explorers, who reported having witnessed one eating a hummingbird. The naturalist Maria Sibylla Merian created a dramatic illustration of this incident, which promptly did the Victorian equivalent of going viral.
In truth, being a ground-based predator the Goliath birdeater’s diet is unlikely to include many birds. But the opportunistic spiders have been recorded snacking on frogs, toads, lizards and small mice.
In the wild, Goliath birdeaters are rarely encountered
This diet obviously helps to boost their size, but it also makes them a bigger target for predatory mammals and birds. Fortunately, they have powerful defences.
«The large South American species possess particularly irritating hair on the abdomen, which they rake off into the air with the spines on their rear legs,» says Gallon. «These tiny irritant hairs waft in the air and settle on the mucus membranes – eyes, nose – of would-be attackers and discourage them.»
For true giants, it is not enough to be big: they have to be hairy too.
