Let’s face it, many of us are scared of spiders – especially the large ones we sometimes come across in day-to-day life. But what is the biggest spider in the world? And how big does it actually get?
First, the largest spider could be determined by its body weight. You might also measure it by the length of the body. Because of this, you could call two different spiders “the biggest spider in the world.”
But most of the time, we refer to the biggest in terms of size and that’s exactly what I’ll be sharing in this article. However, I’ll also mention the biggest spider in terms of weight that used to exist and the one that is still present today.
You’ll also learn where these spiders live and I’ll share more about their size, diet, and whether or not they’re dangerous to humans.
So, read on to learn about the 11 biggest spiders in the world!
