Corpuscular components of the coelomic fluid were observedin Sipunculus nudus using cytochemical and cytoenzymatic methods.In particular, granulocytes were studied and two differenttypes, based on morphology, chemical composition, and functionwere distinguished. Cell aggregates, identified as stem cells oftype II granulocytes, were also evidenced. Besides, empty vesicles,vesicle fragments, laminar structures and brown bodies wereobserved. Based on the observation of their structure and ultrastructure,brown bodies were attributed with the function of accumulatingforeign material, as well as aged components typical ofthe coelomic fluid.
