Diverse shark assemblages have been documented in coastal areas across the globe, however few studies have investigated the long-term spatial interactions of shark communities. This study examined the spatial interactions of six co-occurring shark species in a tropical embayment using passive acoustic telemetry. Eighty-two sharks were tracked in Cleveland Bay, Queensland between 2008 and 2014: The Australian sharpnose shark Rhizoprionodon taylori (8), the spottail shark Carcharhinus sorrah (16), the creekwhaler C. fitzroyensis (8), the pigeye shark C. amboinensis (23), the blacktip reef shark C. melanopterus (17), and the Australian blacktip shark, C. tilstoni (10). Monthly activity space size was similar between species, however annual results showed that the smallest species, R. taylori, had the largest activity space. These results were surprising as they indicated body size had a limited influence on the space use patterns of the collective assemblage. Spatial overlap analysis revealed species experienced some overlap at the extent of their range; however most species exhibited low core activity space overlap. Low core overlap suggested populations had unique resource preferences or may have avoided each other to limit competition. The exception was C. amboinensis, C. fitzroyensis, and C. tilstoni, which had high spatial overlap. Dietary data showed these species likely target different prey. As high spatial overlap could result in unsustainable competition, our results suggest these species limit competition with dietary rather than spatial partitioning. Our study indicates multiple potential mechanisms enable long-term coexistence of shark species.
