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).

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
