Has anyone so far compiled a list of all the animals who can't swim or walk underwater (and can therefore be fenced in with only a moat)? Or does it say in the Zoopedia somewhere I can't see? So far the only ones I've tested personally and found this to be true for are mandrills, red ruffed lemurs and ringtailed lemurs. I would guess some of the other primates and presumably the tortoises and land-based birds are the same but I haven't tested yet.
