    Abstract:
    Mexico is home to a broad biodiversity of shark species, and more than half of the sharks in Mexican waters are distributed in the Mexican Pacific, with over 62 species recorded. This high biodiversity is the result of numerous and diverse marine and coastal environments, including the dynamic Mexican seas, where circulation and spatial variation of oceanic currents is complex, and the seasonal variation of isotherms can be substantial. In the Mexican Pacific we can distinguish some patterns of species distribution, with temperate water and subtropical species found in the northern regions, and tropical conditions and species found in the south. Due to the blending of cold and warm waters, however, we can find a mixture of subtropical and tropical sharks in northern regions seasonally, off the west coast of the Baja California Peninsula and in the Gulf of California, and these areas contain the highest shark species richness. In this chapter we described the shark species biodiversity occurring in the Mexican Pacific, review their conservation status in a regional and global context, and summarize the main conservation measures and issues associated with their management.
