What characteristics do Lake Van and Lake Tuz have in common?

Lake Van and Lake Tuz are lakes that share multiple common features between themselves, despite them being relatively far away from one another.

Both of these lakes are located in Turkey, and both of them are major lakes in this country.

Both lakes are saline lakes, having very high salinity, especially in the warmer part of the year.

Because both lakes have highly saline water, they do not freeze in winter, despite the extremely low temperatures.

These two lakes are extremely poor in biodiversity because of the high salinity.

Both lakes are tectonic lakes, being situated in tectonic depressions.

Neither Lake Tuz nor Lake Van have outlets, so they just take in water from several sources, and lose their water through the high rates of evaporation in the warmer months of the year.
