Clione in a Jar 2

     Large glass jars stored in the refrigerator, with fresh seawater replaced a few times a day, provide decent housing for Clione.  So long as it's cold, they live just fine for up to a month without food.  The largest problem is what we call "white wing disease", which manifests as white, gnarled wingtips.  All evidence points to white wing coming from Clione's wingtips repeatedly brushing up against the glass walls of the jar (they just never stop swimming).  Naturally, this isn't a problem for them in nature because the open ocean does not contain walls.  Here, I've simply opened the door of the refrigerator and snapped a quick picture.
