Laws are like cobwebs, which may catch small flies, but let wasps and hornets break through.

This is the dragline spun by scytodes, the spitting spider.

Most spiders use copious amounts of silk, and silk is essential to their survival and reproduction.

Some of them are orb weaving spiders and some of them are non orb weaving spiders.

These are spinneret glands on the abdomen of a spider.

For example, this garden spider can make seven different kinds of silks.

So this means that both spiders and spider silk have been around for 380 million years.

It doesn't take long from working with spiders to start noticing how essential silk is to just about every aspect of their life.

So silk comes out of the spinnerets, and for those of us spider silk biologists, this is what we call the business end of the spider.

I'm afraid of spiders.

How does an individual spider make so many kinds of silk?

To borrow from the writings of a spider named Charlotte, silk is terrific.

What about a wolf?

Tom hates spiders.

I'm really scared of spiders.

This is a picture of the spinnerets coming out of a spider and the silk being formed from a spider. Isn't that beautiful?

The frame and radii of this web is made up of one type of silk, while the capture spiral is a composite of two different silks the filament and the sticky droplet.

And the spider's web is for the reins on the horse.

She shrieked whenever she saw a spider.

In addition to these biomimetic applications of spider silks, personally, I find studying spider silks just fascinating in and of itself.

There are over 40,000 described species of spiders.
