Oh this one is hard. I have many favorites. I'll give it a try though...
* África: Meerkats - cute and fun and a favorite in real life as well.
- Runner ups: African penguin, African Elephant, african wild dog
* Asia: Lar Gibbons - love how active and vocal they are. I prefer them over the siamang because of the color variants and their size.
- Runner ups: red panda, ASCO, Indian peafowl, Clouded leopard, Komodo dragon
* Oceanía: Kiwi - unique little bird, love their animations and great model.
- Runner ups: Cassowary, platypus, red kangaroo.
*Europe: mute swan - without a doubt. The most interesting and beautiful animal that we got from Europe.
- Runner ups: fallow deer, Grey seal, Alpine ibex, iberian lynx
*North América: Californian sea lion - i love pinnipeds. They are very entertaining to look at. Sea lions are essentials for every zoo.
- Runner ups: prairie dog, beaver, american bison
* South América: jaguar - my favorite big cat and my favorite SA animal irl. They could look better ingame but i still think is one of the best animals from South América that we got.
- Runner ups: capybara, maned wolf, giant otter, giant Anteater, nine banded armadillo.
