What is the world’s biggest spider that ever existed?

According to Guinness World Records, the biggest spider in the world is called the South American Goliath Birdeater, and its scientific name is Theraphosa Blondi. It is possible for its legs to reach a length of up maximum 1 foot (30 cm), and it can weigh up to one ounce (170 grams).

It takes the spiders around 2 to 3 years to reach maturity. As per the Natural History Museum, creepy-crawlies are able to repair injured or lost limbs because they continue to molt until maturity.

Since the Goliath Birdeater is a sort of tarantula, it continues to shed its skin even after reaching adulthood. The beast is capable of growing to be as long as the forearm of a toddler and weighing more than 6 ounces which is equal to 170 grams.

How does the Goliath Birdeater survive?

In human care, they may live for 10 to 15 years. In contrast to males, females may live up to 20 years. The spider is equipped with three different lines of defense. It does this by rubbing their legs against its belly, which generates a swarm of tiny, barbed hairs which may penetrate the mucous membranes of the eyes and cause acute discomfort that can last for days.

In order to protect itself, the Goliath Birdeater employs two kinds of hair: brown and white. The spider will make a hissing sound when it senses danger by rubbing its first two pairs of legs together. This sound may be noticed up to 15 feet away.

It possesses fangs that are one and a half inches long and are sharp enough to puncture the skull of a mouse. In addition to that, it is able to produce a hissing sound by pressing their hairs together, which produces a noise similar to that of ripping Velcro apart.

The Goliath Birdeater does not typically consume birds, despite the fact that it is more than capable of doing so. Instead, it consumes whatever it is able to discover on the ground, which is often earthworms, frogs, or even other tiny invertebrates. It then uses its long fangs to inject poison into its food.


Goliath Birdeater is considered by many of the people who live in the north-eastern region of South America to be a delectable snack. They begin by burning off the hairs that cause the itching, then they wrap the spider inside banana leaves and cook it.


This species has the ability to consume not just birds but also insects, rodents, lizards, frogs, and other animals that are smaller than it is. As its name implies, it is particularly fond of eating birds. Cockroaches are one of the foods served at the Smithsonian National Zoo.

What’s the Reproduction and Development process of the world’s biggest spider?

After going through the maturation molt, males acquire a “finger” on the bottom of the first pair of front legs. This “finger” is used to catch and lock the fangs of the female, as well as to stabilize themselves when they mate. Males only live for a few months after mating before passing away.

In order for the female to reproduce, she has to have recently gone through a molt; otherwise, any sperm that she has obtained would be wasted during the molt. After mating, the female spins a web wherein she deposits anything from fifty to two hundred eggs, which are then fertilized as they leave the body of the female.

The female tarantula will then roll the eggs into a ball and, in contrast to other subspecies of tarantula, she will carry the egg sac with her everywhere she goes. Egg sacs are about the size of a tennis ball and can hold up to seventy developing spiders at a time.


They have to go through a number of molts before they may progress in size. Molting seems to be the process that tarantulas go through in order to lose their old exoskeleton and replace it with a new one that is bigger.

It is normal for Spiderlings to go through five or six molts throughout their first year of life. It usually takes them between two and three years to attain their full development.
