Soft body parts will have signficant shrinkage. This has been demonstrated conclusively with vertebrates, specifically with larval and juvenile fishes. With vertebrates, as they get larger, the signficance of this shrinkage tends to be less. I would expect similar results with inverts, except th

Change in linear dimensions of soft tissues in larval insect when fixed Dear Ecolog-Listers: I have nearly ca. 200 museum specimens of aquatic larval insects (1-3 cm long) that I assume were killed by dumping them in (at the minimum) 70% ethanol. In the only one case that the label states anythin
