Resumen

The Northeast Atlantic hosts several chondrichthyan species, including the iconic yet critically endangered white shark Carcharodon carcharias (Linnaeus, 1758), whose presence remains extremely rare, as reflected in the scarcity of records in this region. Due to the uncertainty regarding its distribution and abundance, this study compiled and updated scientifically confirmed reports of this species. A total of 24 records were identified, of which 22 derive from the scientific literature, including accounts dating as far back as the 16th century. The two remaining records correspond to the first confirmed white shark occurrences in north-western Spain, observed off the coasts of Galicia and Asturias in 2021. Given their exceptional rarity and similar size, it is hypothesized that these sightings involve the same individual. These novel records highlight the potential role of citizen science in monitoring this elusive species in the region.
