This project focuses on understanding the spatial ecology of two vulnerable shark species - smooth hammerheads (Sphyrna zygaena) and blue sharks (Prionace glauca) - along the southern coast of Portugal. This initiative is driven by the need to fill critical gaps in knowledge about shark behaviour, migratory pathways, and nursery habitats in a region facing significant anthropogenic pressures, including fishing and coastal development. These habitats are essential for the survival and recovery of these threatened species, making their identification and protection a conservation priority.
