Abstract

This study documents the occurrence, seasonal patterns and reproductive activity of the sand tiger shark (Carcharias taurus) within a no-take marine protected area in southeastern Brazil, using Baited Remote Underwater Video (BRUV) and diving records. We recorded the species in the Alcatrazes Archipelago during both summer and winter, including pregnant females and reproductively active, non-pregnant females with fresh mating wounds. These findings enhance understanding of the population dynamics of this critically endangered shark and highlight the ecological and conservation value of marine protected areas in supporting individuals across life stages and reproductive conditions year-round.
