1. Xenesthis monstrosa Spider
The Xenesthis monstrosa is a species of spider from the Theraphosidae family.
Also known as the Giant Black Colombian Tarantula, this spider can reach up to 23 cm in leg span. They are typically black with varying brown and red hairs depending on their environment.
As of May 2020, these spiders have been found in Colombia, Venezuela, and Panama. The Giant Black Colombian Tarantula is an aggressive predator, feeding on large insects, small lizards, and rodents. However, they are completely harmless to humans.


2. The Capuchin Monkey Spider
The Capuchin Monkey Spider is one of the rarest spider species in the world, measuring around 20 cm in size. Its diet consists of insects, and although it possesses potent venom, it does not pose a danger to humans. A bite from a juvenile spider might cause a sharp pain and itching. This species is popular as a pet among enthusiasts.
Known as the Hercules Capuchin Monkey Spider, it was first documented in Nigeria about a century ago, and the specimen is currently housed at the Natural History Museum in London. Its name comes from the resemblance between its legs and the fingers of a capuchin monkey, though it doesn't actually feed on monkeys. The Pelinobius muticus species, often referred to as the Capuchin Monkey Spider, is native to East Africa and can grow up to 7.9 inches (20 cm). These spiders are purebred and venomous.
Habitat: While the Hercules Capuchin Monkey Spider may be extinct, smaller species of this spider are available as pets (though they are often not accurately identified as Hercules spiders). These tarantulas tend to be aggressive, making them unsuitable for beginners.


3. Poecilotheria Rajaei Spider
This species of spider is found only in Sri Lanka and India, featuring a striking color pattern with a pale pink and gray abdomen. Known for its fast movements and potent venom, it can kill small animals like mice, birds, and snakes. Poecilotheria Rajaei prefers to reside in fallen tree trunks, rock crevices, or even old buildings.
First discovered in 2009 in Sri Lanka, these spiders prefer living in mature trees. However, due to habitat destruction, they are now often found in old buildings in India. With a leg span of around 20 cm, their abdomen displays a unique pale pink and gray coloration.
This spider is recognized as one of the rarest giant spiders, and its venom, while deadly to small creatures, is harmless to humans.
Though once common in large trees, the Poecilotheria Rajaei is now increasingly rare due to deforestation in Sri Lanka. It is known for its tendency to remain in one location until it faces danger or its shelter is disturbed.


4. Golden Silk Spider
The Golden Silk Spider, or Nephila clavipes, is commonly found in North America. An adult Golden Silk Spider can reach a body length of up to 20 cm, with females being larger than males.
While the Nephila spider is venomous, it is most notable for its ability to spin enormous, sturdy webs to capture prey. The length of these webs can reach nearly 2 meters, making it impossible for small insects to escape. Even small snakes and birds can become unintended victims of the Golden Silk Spider’s web. Their primary diet consists of insects, small birds, and snakes.
In addition to their impressive web-building skills, Golden Silk Spiders have an intriguing courtship behavior. The male spider must massage his mate when she becomes tired, or he risks being torn apart immediately.


5. Camel Spider
Solifugae, also known as wind scorpions or sun spiders, can grow up to 12-15 cm in length. They primarily inhabit dry, arid climates and hunt ground-dwelling arthropods and small animals. While these giant spiders rarely attack humans, their claw-like pincers can pierce the skin, causing painful bites.
Often found in desert regions, the Camel Spider gets its name from its camel-like yellow color. It resembles a hybrid between a scorpion and a spider, with large pincers (fangs) used for biting and producing loud, unsettling sounds. If you're not quick on your feet, this spider can chase you, reaching speeds of up to 10 miles per hour (16 km/h). Fortunately, it is non-venomous.
Habitat: Found in warm deserts or shrublands, but never in Antarctica.


6. Brazilian Wandering Spider
The Brazilian Wandering Spider, measuring around 15 cm, isn't the largest spider, but it's undoubtedly one of the most terrifying. Known as the world's most venomous spider according to the Guinness World Records, it has an aggressive nature and primarily inhabits areas with banana plants, hunting its prey by injecting venom.
This spider is incredibly toxic, with its venom capable of killing a person within two hours.


7. Cerbalus Aravaensis Spider
The Cerbalus Aravaensis was first discovered in 2007 by Dr. Gershom Levy of the Hebrew University of Jerusalem. By 2009, more specimens were found in the sand dunes of Israel.
This black-and-white spider, measuring up to 14 cm in body length, resides primarily underground, using its burrows as ambush points to launch lethal attacks on prey. Unfortunately, it faces a significant risk of extinction due to habitat destruction.


8. Goliath Birdeater Spider
The Goliath Birdeater spider, known scientifically as Theraphosa blondi, is an enormous species that can make your heart skip a beat upon sight.
This tarantula is the largest spider in the world, with a leg span of up to 30 cm and a weight reaching 170 grams. It is found in the high-altitude rainforests of South America, including areas of northern Brazil, Suriname, Guyana, and southern Venezuela.
Its body is covered in intimidating hairs, and despite having eight eyes, its vision is relatively poor. Goliath Birdeaters are nocturnal, spending the day hiding in burrows they've dug themselves or abandoned by other creatures. Their fangs can grow up to 2 cm long, capable of piercing the skin of their prey, and their venom causes mild swelling and pain but is not fatal to humans.


9. Huntsman Spider
Huntsman spiders are often dubbed '8-legged monsters' and can grow up to 30 cm in length. Famous for their large size, the legs of a male huntsman can extend to about 12 inches (around 25 cm).
These spiders are also known as 'giant crab spiders' or 'wood spiders' because they prefer to live in areas filled with wood, such as forests or sheds.
Belonging to the Sparassidae family, which includes over 1,000 species, huntsman spiders inhabit warm tropical climates around the world, including regions in Australasia, Asia, Africa, the Americas, and the Mediterranean Basin. They are particularly common in Australia, but have also been found in areas of the US, Pakistan, India, China, and Japan.
Unlike most spiders, huntsman spiders do not spin webs to catch prey. They primarily hunt insects but occasionally target small reptiles like lizards and geckos. Huntsman spiders use venom to stun their prey before digesting it. In Australia, a huntsman spider was even observed dragging a mouse.


10. Brazilian Pink Bird-Eating Tarantula
Despite its name, this giant spider doesn’t actually feast on birds. Instead, it preys on insects, frogs, lizards, and small rodents. The Brazilian Pink Bird-Eating Tarantula gets its name from its brown body and the pinkish hairs that resemble salmon skin. It can shoot these hairs to incapacitate its prey. This massive spider can grow to 25 cm, including its leg span, and is native to Brazil’s rainforests.
The males have longer legs than the females, but the females are heavier, weighing over 100 grams. This large tarantula is known to breed easily in captivity and is generally considered docile. However, when threatened, it can deliver a bite with pain comparable to that of a cat’s scratch.
In the wild, this species inhabits the forests of Brazil. However, the Brazilian Pink Bird-Eating Tarantula is also a popular pet in many countries, and it is common to see them in pet stores.
