I believe that this is actually a maned wolf, as the caption has the wrong label on it. I like how you uploaded the deer and wolf photos at the same time as the resemblance is startling. There are certainly a lot of South American species that rarely ever make it into North American or European zoos, so thanks for the photos!
I hope that you guys recognize that I was being sarcastic when I commented that the photo caption was labeled incorrectly, as with 180 zoos under my belt I definitely know what a maned wolf looks like. It was interesting to see the photos being uploaded yesterday as the maned wolf and marsh deer shots came up at the exact same time and it was startling to see the resemblance between the disparate species.
