“…Sexual segregation in great hammerhead sharks has not been reported in fishery-based studies (Stevens and Lyle, 1989;Cliff, 1995;Piercy et al, 2010;O'Connell and Leurs, 2015;Raoult et al, 2019;Hsu et al, 2020), unlike other hammerhead species, such as the scalloped hammerhead sharks (Sphyrna lewini, Griffith and Smith, 1834) (Klimley, 1987;Stevens and Lyle, 1989;Harry et al, 2011;Noriega et al, 2011); or other marine species (Sims, 2005;Wearmouth and Sims, 2008). Yet, all three studies conducted on the great hammerhead sharks in Bimini, Bahamas, show a female-dominated population (Guttridge et al, 2017;Heim et al, 2021;Guttridge et al, 2022). In contrast to our results, the few males identified in Bimini are observed during the same period as the females (i.e., December to May), which could be explained by the provisioning occurring in Bimini, attracting all sharks within range of the olfactory stimulus and could suggest that male great hammerhead sharks in Rangiroa and Tikehau atolls remain at a distance from the passes during the austral summers (e.g., off-shore or within the lagoon).…”
