Animal habitat
The Sado Estuary near Setúbal is home to one of the very few resident populations of bottlenose dolphins in a European estuary. This group of dolphins is unique in Portugal as they do not migrate, instead choosing to live year-round in the shallow, nutrient-rich waters of the Sado River. The population currently consists of approximately 27 to 30 individuals, each carefully monitored and identified by researchers through their unique dorsal fins. As part of the Sado Estuary Natural Reserve, the dolphins are protected by strict regulations that limit boat interference to ensure their well-being and natural behavior. Licensed boat tours offer visitors the opportunity to observe these charismatic marine mammals as they hunt, play, and socialize in their natural habitat. The estuary also serves as a critical wetland for numerous bird species, including flamingos and storks, making it a hotspot for biodiversity. Protecting this delicate environment is crucial, as the small dolphin population faces threats from pollution and increasing maritime traffic. Their continued presence is a testament to the ecological importance of the Setúbal region.
