Functional morphology of the sperm‐containing chambers of the sea slug Okenia polycerelloides in the context of sexual selection

Abstract: Sea slugs are interesting models to study post-copulatory sexual selection in simultaneous hermaphrodites due to the enormous variation of their reproductive systems. However, the knowledge of the functional morphology of their reproductive system is limited to few species, and it is rarely discussed in the context of sexual selection theory. In this study, we investigated the functional morphology of the spermcontaining chambers (i.e., ampulla, seminal receptacle, and bursa copulatrix) of the reproductive sys… Show more

“…In snails and insects, the bursa copulatrix enables short‐term sperm storage (Nakahara & Tsubaki, 2007), the degradation of supernumerary sperm cells (Roth, 1960; Sales & Marian, 2020) or the digestion of spermatophores (Meslin et al ., 2015). Although males of some bee and ant species ejaculate directly into the queen spermatheca [e.g.…”
