Nematode and egg


High detail image of a soybean cyst nematode and its egg, magnified 1,000 times. Who's hungry?


 * Nominate and support. -  BRIAN  0918 00:02, 25 July 2006 (UTC)
 * Support Its kinda sickening, but very encyclopedic, sharply focused and well qualified as a FP. SteveHopson 00:06, 25 July 2006 (UTC)
 * support Beautiful image, plenty of detail and an enormous size. A little more information in the description would be nice like what its on (it looks like paper to me?) but otherwise a good candidate IMHO. --WikipedianProlific(Talk) 00:10, 25 July 2006 (UTC)
 * Weak Oppose. Unextraordinary and insignificant; however, the quality is FP material. -- AJ24 01:10, 25 July 2006 (UTC)
 * Unextraordinary and insignificant? Can you elaborate? Does it not illustrate the article well? Which criteria at What is a featured picture? do you believe it doesn't fit? &mdash; BRIAN 0918 &bull; 2006-07-25 04:22

 * Support What an incredible image! By far the best EM so far. I really can't see how these are "insignificant". It is an entire phylum within the animal kingdom which is almost void of illustrations. This is also the best way you could illustrate them without an exploded diagram. --liquidGhoul 06:43, 25 July 2006 (UTC)

 * Question. I really like this image, but have been troubled about something since it was first nominated. The caption says "...nematode, and its egg", but there's no way (that I can see) that this egg belongs to this nematode. It doesn't really gel with what the article says about the life-cycle either. Now perhaps this is a recently hatched nematode alongside another unhatched egg, or something like that, though again I'm not sure how that fits with the described life-cycle. I tried to do some other research on the site it says the photo came from, but couldn't find the pic, much less any more details about it. Can you possibly clarify? Thanks. --jjron 09:20, 26 July 2006 (UTC)
 * If it is the egg, there are two explanations I can think of. The article says the males are usually much smaller than the females, and they have a bent tail. This may be the case, as I can see a bend in the tail. Also, the egg may have been pretty old, and continued to grow since it was fertilised. However, I don't know the growth pattern of Nematodes. As they have an exoskelton, it wouldn't make sense that they continue to grow, it has to be stepped. --liquidGhoul 09:44, 26 July 2006 (UTC)
 * This explains it in more detail, the juvenile undergoes two molts while in the egg, when the egg hatches the juvenile is at the second stage. So the edd must expand after it is laid.--Peta 10:47, 26 July 2006 (UTC)
 * To expand, the egg would have to feed in some way - I don't believe this is the case. It can moult in the egg without the egg growing (like a butterfly in a cocoon). Another possibility: this is the dead female that has become the cyst, with a live male (but the caption still seems to be wrong). --jjron 00:38, 27 July 2006 (UTC)
 * Butterflies metamorphose in their cocoon, it is completely different to molting. They will actually die, and digest themselves into a few stem cells so they can be completely "re-built" as a butterfly. Molting, though it takes a lot of energy, takes much less energy than metamorphosis and the nematode either has a primitive yolk, or some way in passing its food through the egg wall (I think it says this on Peta's link). --liquidGhoul 01:02, 27 July 2006 (UTC)
 * Simile. Eggs don't feed. The link was good (thanks Peta), but I didn't see anything about the egg feeding; if it was there please tell me where. The egg may continue to grow while in the female, but surely not thereafter. --jjron 02:32, 27 July 2006 (UTC)
 * Rightio, I read it wrong :?. I think you are right, it is probably a cyst which contains the eggs, but it should be good to ask someone who knows. --liquidGhoul 02:52, 27 July 2006 (UTC)
 * I see no reason a high protion food reserve in the egg cannot let the egg gain volume. Of course it cannot gain mass without feeding, but it can get bigger, by getting less dense. (just a guess) HighInBC 14:15, 27 July 2006 (UTC)
 * Theoretically perhaps, but unlikely. Yes, a gas could be produced inside the egg as part of the molting, which could then allow it to gain volume without feeding. But the eggshell would have to be very soft and flexible to allow it to expand this much (Peta's link suggests there is an eggshell), and unless it was very specially structured to retain this shape, it would tend to become spherical as it expanded (and why would it need to retain this shape?). --jjron 00:41, 28 July 2006 (UTC)
