Fig. 4 in Analysis of major sperm proteins in two nematode species from two classes, Enoplus brevis (Enoplea, Enoplida) and Panagrellus redivivus (Chromadorea, Rhabditida), reveals similar localization, but less homology of protein sequences than expected for Nematoda phylum

Fig. 4 Immunolocalization of MSP in P. redivivus sperm. a Immature spermatozoa extracted from male. MSP localizes in granules. In some cells, MSP has strongest signals in the periphery (arrowheads) (scale bar 10 µm). b Chain of mature spermatozoa extracted from female.
