Banc d'Arguin National Park as grey heron ("Ardea cinerea monicae") and Eurasian spoonbill ("Platalea leucorodia balsaci") and western reef heron ("Egretta gularis") (IUCN, 1987). For marine mammals, endangered species can be seen here all-year round; for example, Mediterranean monk seals, Atlantic humpback dolphins and bottlenose dolphins. Other species can be seen here are orca, the killer whales, pilot whales, Risso's dolphins, dolphins (common, rough-toothed). Fin whales and harbor porpoises are also known to visit the area. Possibly, highly coastal whale species such as North Atlantic right whales, now-extinct Atlantic gray whales were used to be seen here as well. Other baleen whales possibly occur

Toothed whales are fully aquatic creatures, which means their birth and courtship behaviours are very different from terrestrial and semiaquatic creatures. Since they are unable to go onto land to calve, they deliver their young with the fetus positioned for tail-first delivery. This prevents the calf from drowning either upon or during delivery. To feed the newborn, toothed whales, being aquatic, must squirt the milk into the mouth of the calf. Being mammals, they have mammary glands used for nursing calves; they are weaned around 11
