It would be interesting to compare the popularity of animals and their presence in zoos (based on zootierlist for instance). Surprisingly, some animals (like the mara) are very common in zoos yet very rarely requested by the community.
So, I got the Capybara, ASCO, Alpine Ibex, Red crowned crane, and Eurasian Lynx.21. Emu
