An Overview of the Goliath Birdeater Spider

With its colossal mass and body length, the Goliath Birdeater (Theraphosa blondi) comfortably claims the throne as the largest spider on earth. It is second only to the Giant Huntsman Spider in leg span, extending up to an impressive 11 inches.

Cloaked in a mix of brown and black hair, this magnificent spider boasts a robust, heavy body. Its fangs, another distinguishing feature, can reach a length of an inch, adding to its formidable appearance.

Distribution: Where does the Goliath Birdeater Live?

The Goliath Birdeater primarily calls the dense rainforests of Northern Brazil, Guyana, Suriname, and Venezuela home. These creatures of the night retreat to their burrows in damp, swampy environments during the day, emerging under the cover of darkness. 

The Lifespan, Life Cycle, and Reproduction

The Goliath Birdeater enjoys a lifespan that’s noteworthy within the spider world. While males typically live between 3 to 6 years, females can thrive for a stunning 15 to 25 years.

After successful mating, females lay an impressive 100 to 200 eggs. The gestation period lasts approximately two months before spiderlings emerge, commencing their own unique journey. Male spiders, upon reaching maturity, seek out females for mating. They often perish shortly after this act, whereas females return to their burrows to lay eggs.

Behaviour: Understanding the Goliath Birdeater

Despite the Goliath Birdeater’s imposing size and formidable appearance, they generally aren’t aggressive towards humans unless provoked. These solitary beings become active hunters under the cover of darkness, venturing out of their burrows to find food.

Ecology and its Role in the Ecosystem

The Goliath Birdeater’s diet predominantly consists of invertebrates, but it occasionally indulges in small vertebrates like rodents, snakes, and amphibians. Contrary to what their name suggests, they rarely feed on birds. They play a pivotal role in maintaining the balance of their ecosystems by regulating the population of certain pests.

Predators of the Goliath Birdeater

Despite their size, Goliath Birdeaters do have natural predators. Larger mammals and birds of prey often pose a threat, as do some species of wasps. They are equipped with a unique defence mechanism—the release of urticating hairs—that can cause irritation and discomfort, effectively deterring potential threats.

Distinguishing Characteristics

Apart from its size and mass, the Goliath Birdeater is known for its ability to produce a hissing noise—a process known as stridulation. They generate this sound by rubbing their legs together, an act that, when combined with their size and fangs, makes them a formidable presence in the animal kingdom.

Relationship with Humans

Although their size can be unnerving, Goliath Birdeaters pose minimal risk to humans. Their venom is generally mild, comparable to a wasp’s sting. However, their urticating hairs can cause irritation if they come into contact with human skin or eyes, making it advisable to maintain a respectful distance.

Other spiders included among the biggest spiders in the World

While the Goliath Birdeater reigns supreme in terms of size and mass, the vast world of arachnids houses several other species that also boast impressive sizes. Each of these spiders possesses unique characteristics and fills important ecological roles, contributing to the captivating diversity of the arachnid kingdom. Goliath Birdeater is the biggest spider in the World

The Brazilian Salmon Pink Birdeater (Lasiodora parahybana)

As a top contender for the title of one of the largest spiders by leg span, the Brazilian Salmon Pink Birdeater easily stands out from its peers. It owes its unique name to the distinctive salmon-pink colouration that covers its body, lending it an unforgettable aesthetic.

The Brazilian Giant Tawny Red Tarantula (Grammostola mollicoma)

Another noteworthy entrant on this list is the Brazilian Giant Tawny Red Tarantula. Known for its significant size, this tarantula captures attention with its vibrant reddish-brown hair. This distinguishing feature, coupled with its size, makes it a remarkable species within the arachnid world.

The Giant Huntsman Spider (Heteropoda maxima)

The Giant Huntsman Spider earns its place on this list by boasting the title for the largest spider by leg span. With a leg span that can extend up to 12 inches, it slightly surpasses the Goliath Birdeater in this specific measurement. The Huntsman Spider’s remarkable size and distinctive hunting behaviours make it an intriguing member of the spider realm and can also be called biggest spider in the World with longest legs.

These spiders, each remarkable in their own right, collectively underscore the incredible variety that exists within the world of arachnids. Their remarkable sizes, combined with unique behaviours and ecological roles, capture the fascination of scientists and enthusiasts worldwide, inspiring continued exploration and conservation of our planet’s diverse ecosystems.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.
