Special:Badtitle/NS90:Talk:No Body Left Behind/Potential Sub/sister/super-Trope

I came up with a trope, and it seems to be similar to this, but completely ignored the possibility of just avoiding showing a corpse. Here it is: Rapid carcass decomposition. A creature that fits this trope will physically rapidly falls apart after death. At most the body lasts long enough to get a small amount of information if it is examined right away as well as leaving some dust or liquid that can be analyzed if technology/magic permits. Often the knowledge of this trait has been learned by those in the story before the story line begins. Sometimes this decomposition is also dangerous (e.g. the body explodes, probably hurting anyone nearby that is lacking adequate protection). In the dangerous case, the desire to be able to dissect the body and look at whats inside might not come up.

I was wondering if I should make it its own trope, perhaps after some tweaking. Or should I just expand the trope description of No Body Left Behind?
