Biodiversity of Okheania

The world of Okheania is a fabulous environment, largely shaped by gigantic trees, forming an evergreen dense surface with their crowns and a dark, hostile space around the trunks, similar to the Ocean’s depth and simply named “the profundity”. This green “ocean” developed on Earth after the sowing of the megatrees, initially developed in laboratory conditions to cope with the pollution of anthropogenic origin. As such, it forms a unique ecosystem with several well-defined biotopes and a flourishing variety of lifeforms. The dominant organismal group is that of Order Ichthymammalia, descendants of the common mammals that underwent extensive evolution and currently resemble in many ways the fishes that previously lived on Earth. Uniquely, the present ichtymammals evolved in a convergent way to these fishes and many similarities could be established between these new species and the now extinct fishes of the past.
