Description
Ultrastructural changes of the chorion were studied in prehydrated Artemia cysts. After incubation for 12, 24, 48 and 72 hours, in hygrostats (under controlled relative humidity, that range from 19% to 99%), the authors observed in cysts that were maintained (for at least 48 h in 99% of relative humidity, some chorionic alveoli containing electron dense structures. They presume that ions and/or molecules migrate during prehydration from inside the cyst to the alveolar layer.
