Using an exhaustive collection of presence-only records and relevant predictors, we applied temporally explicit environmental niche modelling to study habitat use by a school shark <i>Galeorhinus galeus</i> population in the Southwest Atlantic. As a complementary tool, we developed randomized habitat association curves to assess both the representation of data with biological information and possible intra-population variation in habitat use. Seasonal niche models supported a core area of distribution between southern Brazil and southern Argentina. Marginal seasonal variation in suitability at the northern and southern extremes of its distribution supported the hypothesis that the <i>G. galeus</i> population behaves to some degree as a niche shifter on an annual cycle. Habitat associations revealed regional bias in the collection of records with biological information, and suggested a complex intra-population segregation pattern between sexes and between maturity stages during the cold half of the year. Overall, results supported large-scale partial migrations (i.e. some individuals migrate while others remain resident) of the <i>G. galeus</i> population. This study demonstrates the significance of future regional efforts that focus on producing more and better databases to derive relevant information at a low cost for the management of threatened sharks and their relatives.
