Electron microscopic techniques were adopted to study the comparative morphology of the secretory granules of the epidermal mucous cells of 4 species of brazilian earthworms. 2 main types of secretory granules were described: A first type, presenting a central body with a high electron density and surrounded by a material with variable aspects and electron densities. The second type of secretory granule possesses an homogeneous aspect and a relatively low electron density. The size and the morphology of secretory granules reveal significant variations among the species and also inside a single specie.
采用电子显微镜技术研究了4种巴西蚯蚓表皮黏液细胞分泌颗粒的比较形态。描述了2种主要类型的分泌颗粒：第一种类型，呈现一个具有高电子密度的中心体，周围是具有不同外观和电子密度的物质。第二种类型的分泌颗粒具有均匀的外观和相对较低的电子密度。分泌颗粒的大小和形态在不同物种之间以及同一物种内部都显示出显著差异。
