The likely reason you didn't get a reply when you asked about a http://www.zoochat.com/241/species-list-271270/ last week is because Ueno is a pretty large zoo and a complete list probably isn't publicly available. I have visited, but it is a few years ago and I don't have the time (or memory) to write a list that would have hundreds of entries. There is a list globalspecies.org but it is neither entirely accurate nor up to date.
(I think you're the only zoochatter that lives on Phobos!)
