Aren't black lion tamarins kept at the Adelaide zoo (AUT)?
From the exotic mammals in Australian zoos thread:I believe they were as I remember that there were BLT in a zoo at Australia but sadly no longer.
"*Black (Golden-rumped) Lion Tamarin (Leontopithecus chrysopygus)
Adelaide Zoo had one pair which bred at least once. There were two males and one female up until 2009 or 2010. I don't know if all three died or if they were exported."
