Original – SVG diagram of the internal anatomy of an adult male C. elegans

Reason: Image meets all of the criteria for an SVG diagram (high-quality, pleasing color contrast, clarity of composition, accuracy and technical correctness of contents, etc.), including an avoidance of raster components and the extensive use of 4-tiered layering to create subtle SVG shading effects. Also, image contains complex layer-composition allowing the intestine and vas deferens to appear to "switch" positions as occurs in the actual worm (i.e., the intestine, which is located on the animal's right for most of its posterior length, switches to its dorsal side at its terminus-- this illustration captures this switch, which is very difficult to accurately render as a layered SVG diagram). Image is currently rendering correctly in Google Chrome 23.0.1271.97m-- please notify nominator if any other browser has difficulty. This image is a sequel to a previous Wikipedia featured picture of a hermaphrodite version of the same animal: Wikipedia:Featured picture candidates/C elegans. Accuracy of diagram may be verified at the Wormatlas.

Support Looks good. I did some research with this worm, but only other half, can't attest to the accuracy on the bottom half, but a cursory glance looks accurate. Mattximus (talk) 14:59, 28 August 2013 (UTC)[reply]
Support - this is an excellent, textbook-quality diagram. About the only real criticism is that the anterior section probably could be included, but that's a minor quibble, and is presumably skipped to avoid redundancy with the other diagrams. Adam Cuerden ^(talk) 17:20, 28 August 2013 (UTC)[reply]
Comments - I am confused while the size marker on the left goes beyond the bottom of the tail, and why it doesn't go to the top; whether 'post meiotic spermatids' should be hyphernated; also as someone who doesn't know anything about the topic, the val deferens/seminal vesicle border doesn't seem to be anything - is that right?

Several changes: first, the entire animal is now illustrated, head to tail, as per Adam's suggestion. Also, to go along with this, the size marker has been expanded and stretches the entire length of the body, no more and no less. 'Post meiotic spermatids' definitely requires a hyphen, and it has now been added. Lastly, the border between the seminal vesicle and the vas deferens is meant to be shown as a hollow cutout-- the entire pink area, along with the two distal tip cells, is considered the 'somatic gonad', but I could not find a way to indicate this 3-part fact without creating visual confusion-- the seminal vesicle is the anterior portion of the somatic gonad adjoining the vas deferens, and holds the spermatids; it also contains part of the lumen through which the spermatids are ejected during sex with a hermaphrodite. This portion of lumen does not appear to be considered the 'lumen of the seminal vesicle', though that is where it is located. If you have suggestions on how I might better illustrate this arrangement, please let me know and I will gladly take a shot at it. KDS4444^Talk 07:52, 29 August 2013 (UTC)[reply]

KDS4444 asked me to update my comments, but the comments weren't that significant. I think the current version is better than the nominated version, and if there is any issue I'm happy to support. Grandiose (me, talk, contribs) 12:42, 31 August 2013 (UTC)[reply]

Support an excellent diagram of a model organism. dllu (t,c) 03:29, 31 August 2013 (UTC)[reply]
Comment: I'm wondering if the use of the tilde to indicate approximation (~0.75mm) is considered technically correct in such contexts. I usually think ≈ is the more appropriate symbol, but I'd understand if ~ is preferable due to it being in ASCII, font support, etc. --Paul_012 (talk) 06:35, 5 September 2013 (UTC)[reply]

You have made me question my thinking here, Paul_012. The Wikipedia article isn't even much help. But I have now consulted with a mathematician friend, and he tells me that ≈ usually denotes precise approximation whereas ~ denotes rough approximation as well as many other things— i.e., ≈ is used in very specific circumstances to indicate very specific but still approximate things, and ~ is used in much broader circumstances to indicate values of lesser precision, among other uses. Given this, and given that my scale is not meant to suggest any precision of estimation beyond the fact that the male form is consistently somewhat shorter/ smaller than the hermaphrodite (which itself is ~1 mm in length) I am going to say that the use of the tilde here is maybe the correct one... though the use of ≈ might not be incorrect! How does that sound?? KDS4444^Talk 18:45, 6 September 2013 (UTC)[reply]

Sounds reasonable. Would support either way, but I notice I'm a bit late. --Paul_012 (talk) 14:03, 7 September 2013 (UTC)[reply]
