James P. Rule was supported by an Australian Research Council Discovery Project (DP180101797). Thanks to Monash University's Anatomy and Developmental Biology department (in particular, Bonnie Dopheide, Stephen Thompson, Justin Adams) for providing space for the dissection. Thanks also go to Museums Victoria for access to dissection equipment and the Mammalogy collection (in particular, Karen Roberts and Steven Sparrey). The following members of the Evans EvoMorph lab and Adams Lab also assisted with the dissection: Lucy Costello, Kathleen Garland, Ruairidh Duncan, William Parker, Jake Kotevski, Jack O'Connor, Natasha Nosiara, Jonathan Edwards, and Ramon Ciccone. CT scanning was performed with the valuable assistance of Alexander McDonald and Dr. Michael De Veer at Monash Biomedical Imaging. The authors acknowledge the facilities and technical assistance of the National Imaging Facility (NIF), a National Collaborative Research Infrastructure Strategy (NCRIS) capability at Monash Biomedical Imaging (MBI), a Technology Research Platform at Monash University. Thanks to Daniel Latorre for discussions around anatomical terminology. The quality of this manuscript was improved thanks to feedback from the associate editor Frank Fish, Krista van der Linde, and two anonymous reviewers. Open access publishing facilitated by Monash University, as part of the Wiley ‐ Monash University agreement via the Council of Australian University Librarians.

N2 - While terrestrial breeding in polygynous species of pinnipeds allows for observations of reproductive behavior (Atkinson, 1997), similar opportunities are limited for cryptic, nonpolygynous, aquatic-breeding species. The isolated nature of solitary leopard seals (Hydrurga leptonyx; Southwell et al., 2012) restricts data collection on their reproductive behavior. Observations on reproductive behavior are limited to mating calls (Rogers, 2017; Rogers et al., 1996) and pupping (van der Linde et al., 2022). Leopard seal mating has been observed in captivity (Marlow, 1967), but not in the wild (Kooyman, 1981). Currently, the leopard seal is thought to mate aquatically, with males defending territories for mating (Atkinson, 1997).
