Actually, I had to look that one up when I was starting the thread.

According to several sources, the big male gorillas often weigh over three hundred pounds but have never been known to exceed five hundred pounds in the wild. In captivity, however, there are records of gorillas who had become obese as a result of bad diets fed by zookeepers back before they really understood what gorillas ate in the wild. Phil the Gorilla star of the St. Louis Zoo weighed in at 776 pounds after his death...and he had been lingering and not eating for a while before he expired.

So, I guess that an eight hundred pound gorilla is a possibility...
