Abstract:The author reports the surface structure of Mesocoelium ovatum juvenile and mature adult as well as egg by scanning electron microscope observaton for the first time .The appearance of juveniles looks very like the mature adults.They both are covered with folds and spines,though their sizes and some inner structures are different under the light microscope.The juveniles have the sex organs but no egg in the uterus.It is shown that the maturation of surface structure may not be related with the development time.The body surface of juveniles and adults are provided with transverse folds and vertical folds,which only are present at the anterior end and posterior end. The shape and arrangement of the tegumental spines of worms at different maturation are basically uniform,belonging to the single spaced-pattern with pointed grow backword projecting.Several dome-shape papillae are observed around the rim of the oral sucker and acetabulum.They are tentatively identified as sensory organs.The surface of eggshell of M.ovatum including the operculum is generally smooth,and the operculum is thick and prominent.
Keywords:Mesocoelium ovatum   Scanning electron microscope.
