Biggest spider in the world

Introduction:

Spiders are fascinating creatures that come in all shapes and sizes, from tiny jumping spiders to large tarantulas. But when it comes to the biggest spider in the world, there’s no competition. The Goliath birdeater spider (Theraphosa blondi) holds this title, with a leg span of up to 30 centimeters (12 inches) and a body length of up to 11.9 centimeters (4.7 inches). 

Found in the rainforests of South America, these spiders have become famous for their intimidating size and potent venom, which can make them a subject of fear and fascination. Despite their size and venom, Goliath birdeater spiders are not considered a significant threat to humans and play an important role in their ecosystem. 

In this blog post, we will explore the physical characteristics, behavior, habitat, and other interesting facts about the world’s biggest spider, the Goliath birdeater.

Identifying The Biggest Spider In The World:

Identifying the biggest spider in the world can be a fascinating and exciting challenge. There are over 45,000 known species of spiders, and while many of them are small, some can grow to impressive sizes. To determine which spider is the largest in the world, we must consider factors such as leg span, body size, and weight.

The Goliath birdeater, also known as Theraphosa blondi, is currently recognized as the biggest spider in the world. This spider is native to the rainforests of South America and can have a leg span of up to 30 centimeters (12 inches) and weigh up to 170 grams (6 ounces). Despite its name, the Goliath birdeater mostly feeds on insects, rodents, and other small animals, rather than birds. It has earned its name due to its large size and powerful appearance.

Other spiders may come close to the size of the Goliath birdeater, such as the giant huntsman spider (Heteropoda maxima) and the Brazilian salmon pink bird-eating spider (Lasiodora parahybana). However, the Goliath birdeater remains the largest spider species currently known to science.

Physical Appearance Of The Hairy Crawler:

The Goliath Birdeater, also known as Theraphosa Blondi, is an incredibly unique and fascinating spider in terms of its physical appearance. Here is a detailed guide to the physical features of this hairy crawler:

Body: 

The Goliath Birdeater has a large, robust body that can measure up to 12 centimeters (4.7 inches) in length. Its body is covered in dense, brownish-black hair, which serves as both insulation and camouflage in its natural environment.

Legs:

 The spider’s legs are its most striking feature, with a leg span of up to 30 centimeters (12 inches). Each leg has distinct patterns of stripes and bands, with long hairs covering the joints and tips of the legs.

Fangs: 

The Goliath Birdeater has large, powerful fangs that can measure up to 2.5 centimeters (1 inch) in length. These fangs are used for catching prey and delivering venom, although the spider’s venom is not typically dangerous to humans.

Eyes: 

The spider has eight eyes arranged in two rows, with the front pair being the largest. These eyes allow the spider to have excellent vision and detect prey and predators in its environment.

Abdomen: 

The spider’s abdomen is large and round, covered in a thick layer of hair. This hair can be used to trap air, providing buoyancy when the spider crosses streams or rivers.

The Average Lifespan:

15 to 25 years

Goliath birdeater spiders are unique compared to other spider and tarantula species in that the female spiders typically do not consume the males after mating. The females take about 3 to 6 years to reach maturity and can live for an average of 15 to 25 years in the wild. In contrast, the males have a shorter lifespan of only about 3 to 6 years and usually die soon after reaching maturity.

The Stages Of Reproduction:

The reproduction of Goliath birdeater spiders (Theraphosa blondi) involves several stages, which are typical for many species of spiders. Here is an overview of the stages of reproduction for Goliath birdeater spiders:

1. Mating: 

Adult male spiders seek out adult females to mate with. Male Goliath birdeater spiders will approach a female’s burrow and signal their presence with vibrations and pheromones. If the female is receptive, she will emerge from her burrow and the two spiders will engage in mating.

2. Egg-laying: 

After mating, the female will lay her eggs in a special silk sac, which she will attach to the walls of her burrow or nest. The sac may contain hundreds of eggs, which will be fertilized by the male’s sperm.

3. Incubation: 

The female will guard and care for the eggs until they hatch, which can take anywhere from 6 to 8 weeks. During this time, she may forage for food and protect the eggs from predators.

4. Hatching: 

When the eggs hatch, spiderlings emerge from the silk sac. The spiderlings are initially very small, measuring only a few millimeters in length.

5. Maturation: 

The spiderlings will molt several times as they grow and mature. It can take up to 3 years for a Goliath birdeater spider to reach maturity, during which time it will continue to molt and grow in size.

Tastes Like Prawns?

There is a myth that the Goliath birdeater spider tastes like prawns, but there is no evidence to support this claim. In fact, it is not recommended to consume any type of spider, as they can carry diseases and toxins that can harm humans. Additionally, the Goliath birdeater is a protected species in some areas due to its declining population, and it is illegal to capture or kill them. 

While some cultures may eat certain types of spiders as part of their traditional cuisine, it is not safe to consume any spider without proper preparation and knowledge of potential health risks. Therefore, it is advisable to avoid eating any type of spider, including the Goliath birdeater.

Goliath birdeater running speed:

The Goliath birdeater (Theraphosa blondi) is not a particularly fast spider compared to some other species. While it can move quickly when necessary, its large size and weight can make it more difficult for it to run quickly. Studies have shown that the Goliath birdeater’s running speed can range from about 1 to 2 miles per hour (1.6 to 3.2 kilometers per hour). However, despite its relatively slow running speed, the Goliath birdeater is still a formidable predator, using its size and strength to overpower its prey.

Are Goliath birdeaters poisonous?

Goliath birdeater spiders are venomous, but their venom is not considered medically significant to humans. Their bites can be painful and cause localized swelling but are not known to be life-threatening.

Where do Goliath birdeaters live?

The Goliath birdeater is native to the rainforests of northern South America, specifically in the countries of Brazil, Venezuela, Guyana, Suriname, and French Guiana. These spiders are found in a variety of habitats within the rainforest, including the forest floor, burrows, and tree trunks. They prefer areas with high humidity and tend to avoid open areas or areas that are exposed to direct sunlight. The Goliath birdeater’s habitat is threatened by deforestation and habitat destruction, and as a result, its population numbers are declining in some areas.
