Sebkhat Imlili is a remarkable relict wetland in the Atlantic Sahara, roughly 50 km south of Dakhla and around 15 km from the coast. This elongated salt flat holds more than 160 permanent pockets of hypersaline water that shelter a relict population of Guinea tilapia (Coptodon guineensis) – tropical fish surviving as living witnesses of the region's wetter past. Classified as a Ramsar wetland of international importance since 2018, it is a scientifically important refuge for specialised aquatic life, endemic reptiles and migratory birds crossing the Sahara.
