I just received my Ornamental Baboon and Usumbara Baboon from Invertepet. I was really careful about getting them into their new homes, as this is my first experience with any of the more defensive species. The usumbara has a body about an inch or so long. Very small. I remembered all I have read about them on the board and was very cautious. When I opened the container it was in, it took off at a very high rate of speed. I managed to get the lid on quickly, but it almost escaped. After that, I did not want to take any chances with the Ornamental(its about 4 inches or so). So I just gradually took the lid off and let it sit in the cage until it got out on its own. I have to say that Bill from Invertepet was really helpful, answered my numerous questions and responed to all my emails. The T's look great and I am really glad that I ordered from Bill.
