Revillagigedo Archipelago, Mexico: A Probable Calving Area for Common Bottlenose Dolphins (Tursiops truncatus)

Waters around oceanic islands are often consid-ered marine biodiversity hotspots. Their high productivity and complex bathymetry provide refuge, food sources, and nurseries for many spe-cies (Clark et al., 2010; Friedlander et al., 2019). Despite their ecological importance, oceanic islands are often overlooked in area-based pro-tection planning because they are considered pre-served due to their remoteness. However, factors such as illegal fishing and increasing ecotourism with close proximity to marine megafauna make it urgent to document information about key species that inhabit these waters (Aburto-Oropeza et al., 2017; Cisneros-Montemayor et al., 2020).
