Web Addresses Addendum

Once again, I spent more time on an addendum than on the main blog post, last Friday's New Web Addresses. First I thought I would compose a list of amusing domain names using new web address endings. After starting, I realized that I had already provided enough for you to amuse yourself better than I could.

Then I considered expanding on expired domain names, summarizing how thousands of domain names expire every day and are eventually offered for sale. After plowing through different sources, I decided there would be little interest--unless, of course, someone wanted to buy this blog’s domain name. (Contact me directly.)

And then I came across a book and articles on domain names that could be read differently than intended, such as a travel website www.choosespain.com, which might be read “chooses pain.” All the domain names were old, and most of those I checked were either gone or changed and of a sexual nature. (Search for slurls if you like that sort of thing.)

Finally, while getting the trash and recycling containers ready for pick up, I was enwrapped in spider webs. Webs. That’s it! The topic for an addendum on web addresses.

Identifying Spiders by their Web (Addresses)

As spider taxonomy goes, over 40,000 species have been identified and discoveries continue. All spiders produce silk, yet not all construct webs. Of those that do, certain taxonomic families are associated with certain types of webs. Perhaps you’ll recognize some of these. 

Orb webs are generally associated with spiders in the Araneoidea superfamily, particularly those in the Araneidae and Tetragnathidae families, but there are orb-weaver spiders in the Uloboridae superfamily whose webs are quite different. (Photo from smithsonianscience.si.edu)
A triangle spider web built by Hyptiotes paradoxus of the Uloboridae family (Uloboridae superfamily) is an example of a reduced orb web. (Photo from www.flickr.com/photos/myriorama/8142595190)
Funnel webs are generally associated with the Agelenidae family of spiders, yet there are funnel-web tarantula, which fall under an entirely different superfamily. (Photo from fireflyforest.net/firefly/2008/05/12/funnel-web-spider/)
“Funnel” and “tube” (or “tunnel”) denote different shapes; there are webs so labeled and spiders associated with each. Though funnel and tube webs appear similar at their openings, this web appears to extend up the tree and is likely tubular. The habitat of Europe’s tube web spider Segestria florentina is often a building crack. (Photo from tjsgardendotcom1.files.wordpress.com/2012/08/web-tunnel.jpg)
Sheet webs are associated with the Linyphiidae or Hahniidae spider families. While all Linyphiidae webs are interwoven sheets, the shapes vary with the species--platforms, bowls, domes. (Photo from btweenblinks.files.wordpress.com/2014/01/p1030235-e1389481419950.jpg)
This photo isn’t upside down. It’s a dome or tent spider web built by the species Prolinyphia marginata, also known as Neriene radiate, of the Linyphiidae family. (Photo from www.asergeev.com/pictures/k/Spider_web.htm)
Tangled webs are shapeless jumbles of fibers generally associated with spiders of the Theridiidae family, but also with spiders of the Amaurobiidae, Nesticidae and Linyphiidae families. (Photo from blogbydonna.com/wp-content/uploads/2012/09/SpiderWeb3.jpg)
Cobwebs are a version of the tangled spider web. Spiders of the Theridiidae family are also known as tangle-web, cobweb and comb-footed spiders. (Photo from multiple websites)
Mesh spider webs are another version of tangled webs, being similar to but more organized than cobwebs. They’re associated with spiders of the dictynidae family. (Photo from sense-of-place-concord.blogspot.com/2015/08/dawn-to-dusk-summer-at-great-meadows-nwr.html)
The nursery web spider, Pisaurina mira, carries her eggs in a sac and builds a web just before they hatch. Although there are "sac" spiders that construct silken tubes or sacs in protected areas, they don’t build webs. (Photo from www.projectnoah.org/spottings/8152819)
And then there are lots of spider webs that seem rather unique, such as this one--or are there two?--observed in New Zealand. (Photo from bestkindoflost.com/wp-content/uploads/2014/03/Spider-web-2-copy.jpg)
