Summary. – The Mediterranean Pond Turtle, Mauremys leprosa (Family Geoemydidae) is a small to medium-sized freshwater turtle (carapace length up to ca. 210 mm in males, 240 mm in females), widely distributed in North Africa and across the Strait of Gibraltar to the Iberian Peninsula and southern France. Our current understanding of the species’ evolutionary history involves complex patterns of population origination, dispersion, extinction, evolution into two major lineages (each with three sublineages), and human-assisted transport. Populations in North Africa are often isolated from one another by intervening arid terrain, and a complex pattern of local variation in shell markings has occurred. Mauremys leprosa tolerates salt water, and has a high tolerance for polluted freshwater habitats, reduced water levels, and elevated ambient temperatures; carnivorous by preference, it will also feed freely upon vegetation and has been reported ingesting nitrogenous animal and human waste. Nesting occurs once annually in most populations, with mean clutch size ranging from 3.8 to 9.6 eggs, depending on the population, with the incubation period also variable, from 55–108 days in Europe to 25–30 days in Africa, the shorter period there perhaps as a response to irregular and brief pluvial periods under very arid conditions.

Distribution. – Algeria, France, Libya, Mauritania, Morocco, Niger, Portugal, Spain, Tunisia. Occurs widely across northwestern Africa and the Iberian Peninsula into southern France; scattered populations across the Saharan region may represent prehistoric introductions.
