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

Nick Sears demos the Orb

When you look at this orb web, you're actually seeing many types of silk fibers.

There's the aggregate and flagelliform silk glands which combine to make the sticky capture spiral of an orb web.

This is the silk that's used to make the frame and radii of an orb web, and also the safety trailing dragline.

It's been hypothesized that orb weaving spiders, like this argiope here, should have the toughest dragline silks because they must intercept flying prey.

In fact, the toughest dragline in this survey is this one right here in this white region, a non orb web weaving spider.

And He it is Who hath created the night and the day, and the sun and the moon, each in an orb floating.

The 21 species are indicated here by this phylogeny, this evolutionary tree, that shows their genetic relationships, and I've colored in yellow the orb web weaving spiders.

Inventor Nick Sears demos the first generation of the Orb, a rotating persistence of vision display that creates glowing 3D images. A short, cool tale of invention.

So if you ever have the opportunity to dissect an orb web weaving spider, and I hope you do, what you would find is a bounty of beautiful, translucent silk glands.

My dwelling is removed, and is carried away from me like a shepherd's tent. I have rolled up, like a weaver, my life. He will cut me off from the loom. From day even to night you will make an end of me.

In an orb web weaving spider, you can find seven types of silk glands, and what I have depicted here in this picture, let's start at the one o'clock position, there's tubuliform silk glands, which are used to make the outer silk of an egg sac.

The new knitting frames and power looms could weave yarn into cloth much faster than the most skilled artisan weaver working in his own cottage. Caught between fixed costs (the hire and upkeep of their domestic appliances) and falling prices for their products, tens of thousands of families were doomed to become paupers.

He has filled them with wisdom of heart, to work all kinds of workmanship, of the engraver, of the skillful workman, and of the embroiderer, in blue, in purple, in scarlet, and in fine linen, and of the weaver, even of those who do any workmanship, and of those who make skillful works.

Them hath he filled with wisdom of heart, to work all manner of work, of the engraver, and of the cunning workman, and of the embroiderer, in blue, and in purple, in scarlet, and in fine linen, and of the weaver, even of them that do any work, and of those that devise cunning work.
