The sea is actually a water border between the Italian and the Balkan Peninsulas. It's known as one of the relatively shallow seas: the southern part of it is said to be the deepest one. Its maximum depth measures approximately 4,050 ft. Besides Italy, the sea washes the shores of five other countries. Moreover, one of the remarkable features of the sea is its rich flora and fauna. It is a home for hundreds of various seaweed, octopuses, fishes, arthropods and echinoderms.
