In the coastal region of Setubal we often observe specimens of the bottlenose dolphin (Tursiops truncatus), considered one of the faunistic symbols of the region.

The area between the Atlantic Coast ( Galé and Arrábida) and the Sado Estuary is home to one of only three mammals communities residing in the European maritime space.

Groups of these sociable animals, called "roazes", supposedly, from habit of gnaw the meshes that fishermen launch into the sea, seek daily the tide favorable to travel to the estuarine area, addressing themselves to areas of estuaries and marshes, in search of food, mainly cuttlefish, sea bass and mullet, in a consumption that can reach up to ten kilograms per day.
