<p class="MsoNormal"><span style="color:#1F497D">Over my 40 years of work with invertebrates, I have to admit that I never had to fix and/or preserved jellies; my specialty being marine benthos. But I have been told a number of things about the preservation
of plankton. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">One is that some jellies do not like ethanol at all, even after fixation with formaldehyde. I believe that is the case for our small FW medusa
<i>Craspedacusta sowerbii</i>. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The other issue, which is not necessarily one for jellies, is that specimens can become opaque once transferred in ethanol, hence obscuring internal structures that may normally be used for identification or
determining the life stage.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">In both cases, best to leave them in formaldehyde if possible.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
