[Spatial and temporal distribution of physicochemical features in the habitat of whale shark Rhincodon typus (Orectolobiformes: Rhincodontidae) in the north of Mexican Caribbean].

Large groups of whale sharks (Rhincodon typus) are common in the North Mexican Caribbean and gather between May and September each year. We describe their spatial and temporal distribution, and the physicochemical (temperature, dissolved oxygen, light extinction coefficient and salinity) and biological conditions during the presence and absence seasons of R. typus.
