Appearance

The biggest spider in the world is called the Goliath birdeater (Theraphosa blondi). As its name suggests, it is capable of eating birds, but it mostly feeds on insects, rodents, and other small animals. The Goliath birdeater can grow up to 30 cm (12 inches) in leg span and weigh up to 170 g (6 oz), making it one of the largest spiders in existence. Its body is covered with dense hair-like structures called setae, which help it sense its environment.

The Difference Between Male and Female Goliath Birdeaters

Male and female Goliath birdeaters have different appearances. Males are smaller than females and have longer legs relative to their body size. They also have more colorful bodies than females, with brighter markings on their legs and abdomen.

Habitat

The Goliath birdeater is native to South America and can be found in countries like Brazil, Suriname, French Guiana, Guyana, and Venezuela. It prefers living in rainforests or other humid environments where there is plenty of vegetation for cover.

Goliath Birdeater’s Burrows

Goliath birdeaters live in burrows that they dig themselves or take over from other animals. These burrows can be up to 60 cm (24 inches) deep and have multiple entrances for easy access.

Distribution

The Goliath birdeater is found in several countries in South America, including Brazil, Suriname, French Guiana, Guyana, and Venezuela. It prefers living in rainforests or other humid environments where there is plenty of vegetation for cover.

How to Spot a Goliath Birdeater

Spotting a Goliath birdeater can be difficult because it is mostly active at night and spends most of its time hiding in burrows or under rocks and logs. However, during mating season (which usually occurs between November and December), male Goliath birdeaters can be seen wandering around looking for females.

Visiting Zoos

If you’re interested in seeing a Goliath birdeater up close, many zoos keep them as part of their exhibits. Some zoos even have interactive exhibits where visitors can touch and hold spiders under the supervision of trained professionals.

The growth rate of the Goliath birdeater depends on several factors such as temperature, humidity levels, and food availability. On average, it takes about 2-3 years for a spiderling to reach maturity.

Molting Process

As with all arachnids, the Goliath birdeater must molt its exoskeleton periodically to grow. During this process, it sheds its old skin and grows a new one. Molting can occur anywhere from once every few months to once per year depending on the spider’s age and health.

Maximum Size Reached by Adult Spiders

Adult female Goliath birdeaters can reach a leg span of up to 30 cm (12 inches) and weigh up to 170 g (6 oz), making them one of the largest spiders in existence. Males are smaller, with a leg span of up to 25 cm (10 inches) and a weight of up to 80 g (3 oz).

Size Comparison

To put this into perspective, the Goliath birdeater is about the size of a dinner plate or a small puppy. In comparison, most common house spiders have a leg span of less than 5 cm (2 inches).

The Diet of the Biggest Spider in the World: What Does It Eat?

Prey

The Goliath birdeater mostly feeds on insects, rodents, and other small animals. It has been known to eat birds occasionally but this is rare.

Favorite Prey

Some of its favorite prey include cockroaches, crickets, grasshoppers, beetles, and millipedes.

Hunting Techniques

The Goliath birdeater uses several hunting techniques depending on the type of prey it is targeting. For example, when hunting insects like crickets or grasshoppers, it will use its powerful fangs to inject venom that paralyzes its prey. It will then wrap its legs around the prey and crush it with its strong jaws.

Feeding Habits

After killing its prey, the Goliath birdeater will use digestive enzymes to break down the tissues and suck out the nutrients. It can take several hours for it to finish feeding on a large meal.

How the Biggest Spider in the World Defends Itself from Predators

Natural Defenses

The Goliath birdeater has several natural defenses that help it protect itself from predators. Its first line of defense is its size and strength, which can deter many potential attackers.

Hairs on the Body

Another defense mechanism is the dense hair-like structures called setae that cover its body. These setae can cause irritation or allergic reactions in predators, making them less likely to attack.

Behavioral Defenses

The Goliath birdeater also has several behavioral defenses that it uses to protect itself. For example, when threatened, it will rear up on its hind legs and make a hissing noise by rubbing its legs together.

Biting as a Last Resort

If these defenses fail, the Goliath birdeater will resort to biting with its large fangs. Its venom is not lethal to humans but can cause pain and swelling.

Fascinating Facts About the Behavior of the Biggest Spider in the World

Social Behavior

Despite their intimidating appearance, Goliath birdeaters are actually quite docile and solitary creatures. They do not form social groups or colonies like some other spider species.

Mating Habits

Males will venture out of their burrows during mating season to search for females. Once they find a female’s burrow, they will tap on it with their legs to signal their presence. If the female is receptive, she will allow the male to enter her burrow and mate with her.

Life Span

The Goliath birdeater has a relatively long lifespan compared to other spiders, with some individuals living up to 25 years in captivity.

Growth Rate Slows Down as They Age

As they age, their growth rate slows down significantly, and they become less active. Older Goliath birdeaters may spend most of their time hiding in their burrows, only venturing out to feed or mate.

In conclusion, the biggest spider in the world is a fascinating creature that continues to intrigue and amaze people with its impressive size and unique characteristics.
