This paper effectuates a preliminary analysis of the foraminiferal distribution in two coastal lagoons of
northern Africa: Nador (Morocco) and El Meleh (Tunisia). In Nador lagoon, the highest richness of species
was found in the inner margin of the lagoon, with frequent specimens of Ammonia and Quinqueloculina.
A single species (Nonion depressulum Walker & Jacob) was collected near an old iron mine, whereas low
densities and diversities were observed near the artificial mouth. In El Meleh lagoon, high number of both
individuals and species characterize the marine connection. In the remaining zones, these microorganisms
are very scarce (mainly Ammonia spp.), especially near the treatment station of the Slimene town
