Imo animals not held in zoos can be grouped roughly into 3 different categorys:
1. Just why: Animals that have close relatives either in the game allready that are found in zoos or have a relative or functionally identical animal that could easily replace them without any draw backs.
Examples are: Javan Rhino (Indian Rhino), African Forest Elephant (African Elephant), Brown Throated Sloth (Two toed Sloth), Bald Uakari (Literally any other SA monkey actually found in zoos), Saola (Lowland Anoa), Indri (Conqueller Sifaka)
2. Understandable but rather no: Animals that are unique, but wouldnt fit well into the game and add only relativly little compared to other options.
Examples are: Pikas (many other small rodents like guinea pig, agoutis, squirells or lagomorphs that would be preferable), Tarsiers (Unique indeed, but they wouldnt add much to the game that a lori couldnt)
3. Would actually be a good addition: Animals that are unique and got good reasons for inclusion, often are even kept in a small number of zoos:
Saiga (Would flesh out central Asia with its arguably most iconic missing animal, still found in a few zoos in east europe with plans to expand that number), Leopard Seal (Rarly single animals are kept in australian zoos, only option for an antarctic carnivore), Marine Iguana (new diving reptile from the galapagos island), Elephant Seal (Very unique marine mammal, while superficially similar to the walrus, theyd be much more flexible in use)
2 and 3 are ofcours atleast somewhat subjective, but thats how the world is sometimes
