The collection contains images of temporary whole-mount preparations. The images were taken by confocal laser scanning microscopy. The preparations were created using immunohistochemical staining of nervous elements for serotonin and FMRFamide and histochemical staining by phalloidin for muscles. The collection includes images of the central and peripheral nervous systems and neuromuscular interactions in 3 species of rotiferans from 3 families (class Eurotatoria, order Ploima). The collection was created at the Åbo Akademi (Finland) and at the Zoological Institute RAS (ZIN RAS). The images are kept on the server of ZIN RAS (Laboratory of Evolutionary Morphology) and are available from the author.
