The Vanished Sea This episode is set in what was once the Mediterranean, 5 million years in the future. It features three species: (1) Cryptile, a lizard with a sticky frill to catch flies; (2) Scrofa, a descendant of the wild boar which has developed spindly legs to allow it to live on rocky islands in the desert; (3) Gryken, a descendant of the pine marten which hunts Scrofa in the cracked rocks of the landscape. Because of the collision between Africa and the southern tip of Spain, the Mediterranean has been enclosed and dried up, becoming an enormous salt desert with a few lakes of ultra-saline water. The episode follows the mating season of the Cryptiles and Grykens hunting for food.
