How Many Legs Does a Spider Have?

Spiders are known for their intricate webs and unsettling appearance. 

One of the most distinctive features of these arachnids is the number of legs they possess. 

So, how many legs does a spider have? A spider has eight legs.

Spiders have two main body parts:

  • The head and chest are joined together, called the cephalothorax. This is where their brain, eyes, and legs are located.
  • The abdomen is the rear part of their body. It holds important organs and the special parts that make silk.

Spiders have eight legs, which makes them different from insects that only have six. These legs help them do lots of things:

  • Move around: They use their legs to walk and run very quickly.
  • Catch food: Many spiders use their legs to grab and hold onto their prey, like bugs.
  • Build webs: Spiders that make webs use their legs to carefully weave the sticky threads.

Why Eight Legs?

Having eight legs is really helpful for spiders:

  • They stay steady: Eight legs help them balance and walk on all sorts of tricky places.
  • They can move fast: Extra legs make them quick and able to turn and chase their food easily.
  • They feel their way: Their legs have tiny hairs that help them sense what’s around them.

Spider Legs: A Closer Look

Spider legs come in various shapes and sizes, depending on the species. Some spiders have long, slender legs adapted for running, while others have shorter, sturdier legs for digging or climbing.

  • Regeneration: Remarkably, some spiders can regenerate lost legs, although the regenerated leg may be smaller than the original.

Spider Legs in Action

Beyond walking and running, spider legs play a vital role in a variety of activities:

  • Jumping: Some spiders, like jumping spiders, have powerful legs that enable them to leap impressive distances.
  • Mating: Male spiders often use their front legs to perform elaborate courtship displays to attract females.

"My family has been an H2 customer for about 6 months. We built a home in Saratoga Springs, in an area that has a lot of insects and spiders. After seeing a few spiders in the house, we decided to use their services. They were prompt to respond, and very professional. I have not seen any spiders in our house since that time. We have called them for a few other issues (mice and may flies) and they always come right out and help. The staff are very friendly, very helpful and very professional. They never seem bothered by us calling and always ask us to call if something else is needed. They seem to value their customers very much, and they strive to provide a great product. I would highly recommend them based on my experiences."

“These guys are seriously the best! We’ve worked with them since 2017 in our townhome in Eagle Mountain to now when we moved to Sandy! They just came to treat our new home and I feel so much better knowing we’re covered again!

We never saw any bugs at the last place, and two days after we told them we were worried about mice at the townhome, they were there taking care of it.

Amazing customer service and always very thorough!”
