The mouth looks bigger because the mouth is open whereas the other BG have their mouth closed and it appears they have a smaller mouth. The open mouth better shows the maxillary thus is appears larger than that of a closed mouth. I agree with Snipe and Sunil, all the non-crappie in the pic I think are what we standardly call northern strain BG and they probably were caught from clear, light brown stained water. BG from wild natural populations will have a 'fair' amount of natural variation of color. I will next post a link of mouth size variation for the common sunfish (Lepomiis) species. The bluegill does have a small amount of mouth size variation in natural populations that is also noted in this well done video link that has some good useful information.
