ABC Wednesday W for Web





Posted by Picasa

Click to enlarge, please! These photos are taken in my garden.

From Wikipedia:"Spiders initially started producing silk for reasons other than web-making. When spiders moved from the water to the land in the Early Devonian period(416 to 359.2 million years ago) , they started making silk to protect their bodies and their eggs. Spiders gradually started using silk for hunting purposes, first as guide lines and signal lines, then as ground or bush webs, and eventually as the aerial webs which are so famous today.

Spiders produce silken thread using several paired spinneret glands located at the tip of their abdomen. Each gland produces a thread for a special purpose – for example a trailed safety line, sticky silk for trapping prey or fine silk for wrapping it. Spiders use different gland types to produce different silks, and some spiders are capable of producing up to 8 different silks during their lifetime.

Most spiders have three pairs of spinnerets, each having its own function – there are also spiders with just one pair and others with as many as four pairs.

Webs allow a spider to catch prey without having to expend energy by running it down. Thus it is an efficient method of gathering food. However, constructing the web is in itself an energetically costly process due to the large amount of protein required, in the form of silk. In addition, after a time the silk will lose its stickiness and thus become inefficient at capturing prey. It is not uncommon for spiders to eat their own web daily to recoup some of the energy used in spinning. The silk proteins are thus recycled."

What a great W word for the day and the pics are terrific even if they did come from Wikipedia! It's saved my day several times!! The webs are beautiful, so fragile looking and, of course, I always enjoy the information because I always learn something I didn't know! Have a wonderful week, Wil!

Web on the Web was a great choice - especially since it was not about WWW but about something far older and much more intriguing.

PS I wish I could have taken these photos, too :-)

That bottom picture is rather weird!!

Fascinating bit of natural history about spiders and the evolution of silk spinning! Thanks for that. :)

Vicki Lane said...

Wonderful pictures, Wil! And I love the header!

Carol said...

Lovely garden - very industrious spider! I didn't know the spinning of webs utilized protein. Thank you for weaving me into your web.

Ann said...

Ah!!! The windmill, that was what I was taught about Holland when I was studying in school in Sarawak.

Your webs are incredible. I tried to find webs, but have not been very good.

Nydia said...

I have to say that, although knowing how beautiful and artistic a web is, I suffer from arachnophobia, so I had to pass the photos! :oP I can't stand the sight of a spider not even in Harry Potter film, lol!

But you gave precious info about it - and I love trivias - that I haven't known before. :o)

Kisses from Nydia.

Paula Scott said...

Ewe!! Hard for me to look at! I thought this was going to be about the internet web! Ha,ha! Great web shots, though even if I have a bit of a fear of spiders.

Barbara Martin said...

The different spider webs remind me a bit of snowflakes: each being completely different than the next. Lovely photos, Wil.
