How do webs form by pulling threads from their bodies?

Spiders make webs by pulling threads from their bodies, just like you might pull a string from a spool.

Imagine you have a big ball of yarn, and every time you need a thread, you just pull one out. That’s kind of what spiders do, they have a special place in their body called a spinneret, which is like a tiny spool of thread. When they want to make a web, they pull the thread from this spinneret and let it go through the air.

Spiders usually start at one point, like the corner of a window or a leaf. They put down a thread and then move around, leaving more threads behind, kind of like drawing a map in the air with string!

As they walk around, they keep pulling more thread from their spinneret, making loops and patterns that look pretty from far away.

Sometimes, spiders even use their legs to help shape the web or attach it to something else. It’s like you’re building a little house with strings, strong enough for bugs to get stuck in!
