The biggest spider in the world is the site of a small puppy and is a hairy tarantula from the goliath bird-eating species.

This thing is everything you could imagine as a creepy 8-legged species. It’s huge, but don’t let this vision fool you, even though something tells you that it’s dangerous and life-threatening. The goliath bird-eating spider is the biggest but harmless to humans.

Some people might speculate that this creature is big because of its leg span. According to azcentral.com, the birdeater spiders are massive in body size. They are native to South America and can weigh more than 6 ounces.

The biggest spider on record was just over 11 inches across. They do carry venom in their fangs and have been known to bite humans when threatened, but the venom just causes swelling and mild pain for a few hours. Tarantula bites to humans are usually in self-defense.

The female spiders, who traditionally eat the males after mating, can live for up to almost 30 years, according to Nature World News. These giants are so large and hairy that they can even be mistaken for a small mammal. We only know them from horror movies, or nightmares. Can you imagine seeing one of these giant spiders?

The most dangerous thing about the worlds’s biggest spider is its ability to flick urticating hairs from its body at any creature it perceives as a threat, including humans. This is not a species of tarantula you’d keep as a pet. The tiny, almost invisible hairs that it voluntarily sends floating through the air are extremely irritating to our skin, and can cause real problems if they got into delicate mucous membranes around eyes and mouth.

As hunters, tarantulas can be fearsome predators. Tarantulas don’t have any special techniques, such as building intricate webs, or leaping great distances, for hunting their prey. They use good, old-fashioned stealth and strength, very much like wild cats. They sneak up on their prey and pounce on the unsuspecting victim, inflicting a fatal bite with venomous fangs.

One fascinating feature of the biggest spider is their ability to make noise. But when feeling threatened, the goliath bird-eater is capable of making a pretty loud hissing noise by rubbing bristles on its legs together.

Harvard entomologist Piotr Naskrecki recently told National Geographic about the time he came across one of these puppy-sized spiders in Guyana.

“I could clearly hear its hard feet hitting the ground and dry leaves crumbling under its weight … I pressed the switch and pointed the light at the source of the sound, expecting to see a small mammal, a possum, a rat maybe. And at first this is what I thought I saw-a big, hairy animal, the size of a rodent.”

Naskrecki went on to explain that he witnessed the biggest spider on earth, and was terrified. We don’t normally associate spiders with noise, like we do with dogs, cats, birds, etc. This spider can be loud enough to be heard up to 15 feet away.
