Check out this huge silverback gorilla up close. I believe this gorilla weighed around 475lbs. I saw it at the Miami Zoo, and it was incredible to see it up close. What was cool is that the Miami Zoo has this walk-in "cave" that has a very thick window that you can see into the enclosure. This awesome gorilla was sitting right up against that window and provided me an excellent view of the gorilla. From this range it was obvious how powerful this gorilla is. What an amazing animal!
