In the ZOO, but wild by woxys

But think about, you have a super luxus room in Hilton... however you're not allowed to go out. You have fresh air, somebody cares about you, a nice partner, enough food and anything... but the doors are locked forever. Won't you miss it to walk with the people outside? If you're born in this room, I think it's different, as you don't know how it is, to fly with the bird over the sky.
I think, you'll mostly decide for what you're used to, as the animals in freedom will never miss the comfort in a Zoo, as they just don't know it, as well as Zoo animals won't miss the world behind the exhibit for the same reason.

For the Baikal seals I could give you a yes at least it's what they say on their website, I'm not that educated to tell different kinds of seals apart
[link] --> not really good photo... but...however it's maybe also a fur seal, I'm not sure as they seem to have both, I'll tell you more when I'm back from there ^-^

I think animals like Komodowaran, Quolls (at the moment not to shown as they have cubs ~ since 35 years first young Quolls in an European zoo) and I think it always depends on the watcher what is special and what not.

I have no complaints about your English at all. Mine I assume could be better too
