<\/a><\/p>\nThis brings to mind a pet peeve of mine–drawings of impossible webs.<\/p>\n
An \u201corb web\u201d is the well known spider web comprising a series of non-sticky silken lines forming a rough frame used to attach the web to something (trees, posts, small children, whatever) and other non-sticky\u00a0 lines that radiate from the center of the web to support its prey-catching business part.<\/p>\n
Typically, after creating the framework and the radial lines, the resident spider starts at the center of the web and goes \u2018round and \u2018round in a spiral manner, all the while laying a continuous strand of sticky \u201ccapture\u201d silk. The capture silk is carefully attached to each radial line as it\u2019s crossed, thus creating a \u201dnet\u201d for capturing prey on the sticky lines.<\/p>\n
Now, not all spiders make webs, much less these orb webs, but still, it\u2019s what most people think of when one says \u201cspider web.\u201d<\/p>\n
So what\u2019s my gripe?<\/p>\n
Look at this illustration… Now look at this photo of an orb web:<\/p>\n See the problems? In the photo of a real web, the capture lines span the gaps between the radial lines. Some species pull the lines really tight, but others leave a little slack, and when this happens, gravity causes the capture lines to sag…downward<\/strong><\/em>. \u00a0Everywhere.<\/p>\n Look at that photo again, please. Now look again at the illustration.<\/p>\n Take a good look at the drawing of the “spiral” capture lines! Not a chance! How on the Flying Spaghetti Monster\u2019s green earth could the vertical capture lines not only sag uniformly toward the web\u2019s center, but actually sag upwards<\/em> on the lower half of the web?\u00a0Plus, of course, the capture lines in the drawing are concentric, not a continuous spiral.<\/p>\n Now do you see the problem with the \u201cfrozen web?\u201d<\/p>\n A quick image search found this version of the non-cropped photo, where the giant ice \u201cspider\u201d at the bottom\u00a0verifies the entire thing\u2019s ice sculpture roots.<\/p>\n So please, if you\u2019re going to draw orb webs (or crop a photo to claim it\u00a0represents a real, frozen web), remember how gravity works on this planet.<\/p>\n (I won\u2019t even get into the fact that there are two entirely different kinds of capture lines on the ice sculpture…look at the 9:00-10:00 position in the top photo–click on the photo to enlarge it.)<\/p>\n Extra points: \u00a0What’s up with this photo?<\/p>\n <\/p>\n Answer: A neat photo of an ice sculpture was posted on Facebook in January 2016 with the comment \u201cFrozen spiderweb found in Nantucket, Massachusetts.\u201d This brings to mind a pet peeve of mine–drawings of impossible webs. An \u201corb web\u201d is the … Continue reading <\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
