There are actually 5 basic varieties of papillae along the body, but because they are delicate and quickly eroded, their apparent abundance could depend on their density andor the common sample therapy. The papillae is often separated into physique papillae, mouth papillae, genital papillae, shield papillae and interbranchial papillae. Body papillae are present more than at least a part of the physique surface on all species and may have distinct arrangements. They might be evenly distributed over many of the physique, either really densely as in S. fossor, sparsely distributed as in S. scutata, restricted to a specific physique area or region, or in one particular or two transverse rows of clusters or `pompoms’ on some or most segments, as for S. africana Augener, 98 n. status and S. costata. Mouth papillae surround the mouth opening and are usually much more resistant than other papillae present nearby. The largest papillae would be the genital papillae; they may be a pair of substantial, muscular, generally extended conical papillae protruding in the septum in between segments 7. Where they had been not apparent, either because they happen to be lost or are invaginated, the pores via which they extend out could commonly be detected. For some species for instance S. fossor and S. affinis these papillae are quick and narrow, whereas in other species for instance S. scutata, they are significantly longer, extended and broader. The ventrocaudal shield is covered by integument and it has numerous papillae protruding from the surface. On some species they could be quick or filamentous, recurved or projecting at right angles in the shield. On bigger men and women they are typically worn off or missing by way of abrasion; nonetheless, the presence of fine sediment particles offers an indirect indication of their abundance. The interbranchial papillae are extended, w.
