Based on the lemur from "In Her Eyes". She and I just sat there looking at each other and when others came, she ran up to a higher place and i started walking away. She let out this scream that was so painful to hear, it was so sad and it caused other lemurs to scream too. They told me it was a warning scream, that they do that when they see a predator. That very well may be, but i dunno, just felt odd how she did it when i walked away. Call me crazy.

*Edit* this was written before a correction was made to my description of the photo. A slight mix up on my part concerning the lemur's sex and breed. It seems that the center had put a Black Lemur in with the Mongoose Lemurs and the tour guide didn't say anything of it so I had just assumed that the one I saw was a weird variation of a mongoose. (They also did not have 'black lemurs' listed on their website as lemurs they house)
