Summary. – The Caspian Turtle, Mauremys caspica (family Geoemydidae), is a small freshwater turtle species widespread and plentiful throughout the Middle East. Although fully aquatic, it is often found in extremely arid habitats, where high concentrations may exist in small streams. It is rarely used for food, but due to landscape alteration, pollution and intensification of water management, M. caspica is increasingly threatened. The maximum straight-line carapace length (SCL) has been recorded as 25.0 cm for both sexes; however, females are usually larger on average, but males in some populations attain the same size as females.  

Distribution. – Armenia, Azerbaijan, Bahrain, Georgia, Iran, Iraq, Russia (Dagestan), Saudi Arabia, Syria, Turkey, Turkmenistan.

Subspecies. – None currently recognized. Two clusters of mitochondrial haplotypes (eastern and western portions of the range) and four microsatellite clusters have been delineated, defining four Management Units for conservation.

Status. – IUCN 2024 Red List: Global: Least Concern [Not Listed] (LC, assessed 1996); Regional: Europe: Vulnerable (VU A2ac+3c, assessed 2004); TFTSG Provisional Red List: Least Concern (LC, assessed 2011); CITES: Not Listed.

Distribution:

Distribution of Mauremys caspica in Turkey and the Middle East. Yellow dots = museum and literature occurrence records of native populations based on Iverson (1992), other more recent literature records (see TTWG 2017, 2021, in press), and authors’ additional data); orange dots = possibly introduced or translocated specimens. Distribution based on fine-scaled GIS-defined level 12 HUCs (hydrologic unit compartments) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs based on Buhlmann et al. (2009), TTWG (2017, 2021), and data from authors and other sources.
