Mediterranean Salt Flat

The Mediterranean Salt Flat is a very large salt flat or salt pan covering almost the entirety of the Mediterranean Basin, which evaporated after becoming landlocked due to continental drift and falling sea levels. A number of "islands," the highlands of what were once true islands, dot the salt flat, as do limestone plateaus. Most life in the region is to be found on these islands, due to the inhospitable conditions on the salt flat itself.

Though there are a few salty lakes on the flat, the water is far too salty to support fish or complex life, and would be fatal if eaten. All that lives in these lakes are algae and bacteria which can feed on the salty chemical soup, and the shores support thick clouds of saltflies which feed on the algae and bacteria. Little life exists on the surface of the salt flat itself, though the salt-loving bacteria does thrive there, staining the surface red in places. One of the few animals to exist out on the salt is a lizard, the cryptile, which is able to effectively camouflage its white body against the salt.

Most life in the Mediterranean, including animals, exists on the flat plateaus and dry island mountains, where conditions are less harsh. In the highlands of the rocky plateaus, there are plants such as grasses and trees.
