Caspian Sea
The sea has a surface area of 371,000 km (143,200 sq mi) (not including the detached lagoon of Garabogazköl) and a volume of 78,200 km(18,800 cu mi). It has a salinity of approximately 1.2% (12 g/l), about a third of the salinity of most seawater.
Caspian turtle
The western Caspian turtle ("M. c. rivulata") ranges throughout southeastern Europe (former Yugoslavia to Greece, the Ionian Islands, Crete, and Cyprus), Bulgaria, eastern to south-central Turkey, coastal Syria, Lebanon, and Israel; records from the vicinity of Ankara and from Lake Emir are questioned by Fritz. This subspecies has narrow or fine reticulations on its carapace (which may be lost with age), and a totally black plastron and bridge. Age-related flavism may occur, resulting in a mainly yellow plastron with black reduced to the seams. This subspecies can be separated from melanistic "M. c. caspica" by differences in head, neck, and foreleg patterns. Its plastral formula usually is "abd > fem > pect > gul > an > hum" in both sexes, but variations of this have been described in Izmir populations.
