The morphology and fine structure of Cajal bodies (coiled bodies, CB) in the germinal vesicles (oocyte nuclei) of the house cricket, Acheta domesticus have been analyzed. It is shown that in the studied species CBs arise as early as in the youngest previtellogenic oocytes, and are located next to or within aggregations of multiple nucleoli. Surprisingly, two morphological types of CBs have been found in the analyzed specimens. On the basis of EM studies we suggest that they represent subsequent developmental stages of CB morphogenesis.
