it's a sloth, if you're wondering

We visited the Vancouver Aquarium recently to visit our old friend the tropical sloth (I don't think it has a name?). Took awhile to spot it, since it was hiding way up high among the tree blossoms. I tried to get the best photo I could... waited and waited, and then it occurred to me that.. oh yah, it's a sloth... it's going to take forever to move and turn to even face me. So short of poking it with a stick (which is not allowed of course), I would have had to wait a long long time in that tropical heat. So this is the resulting photo... a mysterious fur ball in some branches... I am not even sure which side is the head... I think the top?
