- Аннотация: Order Cyclostomata is a diverse group of ancient sedentary filter-feeders, whose muscle system remains understudied by modern methods. Its reconstruction by histological technique is a difficult task due to the small size of the zooids. Confocal laser scanning microscopy (CLSM) added by transmission electron microscopy (TEM) allow visualization of a complex system of thin muscle fibers, their number and position with much better resolution For this study we have chosen four cyclostome species from four distant families (Crisiidae, Tubuliporida, Lichenoporida, Plagioeciidae). Colonies of Crisia eburnea, Tubulipora sp., Disporella sp., and Diplosolen obelia var. arctica were collected at the White Sea by SCUBA diving, and fixed for both, CLSM and TEM. In all studied species we identified five main muscle groups: apertural muscles, muscles of the membraneous sac, muscles of tentacles and lophophore base, retractors of the polypide and muscles of the digestive tract. Within these groups apertural muscles are the most variable possibly due to the differences in the structure of vestibulum. Other muscle groups are relatively uniform in the studied species. Polypide retractors, muscles of the tentacles and of the pharynx are striated, while the other muscle groups consist of only smooth muscles.
