I came across this video of Quinn the Olive Baboon and the title says he weighs 155 lbs so I asked the uploader if they had verified info on it and the keeper had told them he did weigh that much. I was amazed because usually males average at 60-75 lbs and occasionally a big male will get up to 110 lbs. 155 lbs seems record-breaking for an Olive. I know Chacmas can get to 100 and Mandrills with great nutrition can get to 130. Regardless, this is really awesome and I had no idea they could get that big!!!! Perhaps he's been working out?
