Stepping away from biomes and towards wildlife

I think that although i love the game it lacks in fullness of creatures and wildlife, the oceans seem dull and lifeless due to the lack of marine life. I would love to see some whales, sharks, different species added i to the game. I love the oceans creativity alrhough, the ships and coral are cool. But like i said i think marine life would make the game so much more intriguing and exiting for players, as most players love exploring and finding animals. I also would like to increase wildlife on lands, such as giraffes, elephants, bugs etc. this woukd make the game so much more magical and exiting. I know that these can be added as ‘add ons’ but i love achievements like alot of other players and would love to see this fome to life.
