A new gorilla exhibit was installed at the Bronx Zoo and for a little extra fee you could enter and observe. The gorillas were separated from human contact by heavy glass. There were babies, juveniles, and adults. The interaction was fascinating to watch. One habit that was unique to captivity was one older female I observed. She would eat, chew, regurgitate, swallow, and chew again. It was something that gorillas were seen to do in captivity but not in the wild.
Six degrees of separation: My cousin knows a guy who knows this gorilla – Layla. How about that!! (See the comments)
