Lisbon is where the Tagus river joins the Atlantic Ocean after crossing more than one thousand kilometres along the Iberian Peninsula. The nutrients that flow from the river and Estuary towards the sea allow high productivity along the coast. This productivity depends on algae, phytoplankton and small zooplankton. In turn, these organisms will feed fish shoals and other invertebrates.
Hotspot for sighting Cetacean Dolphins and Whales
Several dolphin species, like the common dolphins, depend on great shoals of pelagic fish. Sardines and mackerel are their main diet. Baleen whales normally feed on small crustacean (Krill) of small shoals of fish. Top predators, like sharks and marine mammals will control food chains and balance ecosystems.
One of the best places in Europe for spotting Dolphins and Whales is, with no doubt, the Azores archipalegos. Whale watching and dolphin watching are fantastic outdoor activities to do with your family and friends.
Nontheless, along the Portuguese mainland, dolphins and whales are also spotted in special places. Because of the high productivity close to Lisbon, around 8 species of Dolphins and Whales can easily be spotted all year round.
During the wild safari odyssey we have created in the sea, chances of sighting marine mammals are very high. Cetacean species which have been sighted frequently close to Lisbon are divided into 2 suborders:
