Anyone here have any pics of any bluegills with protruding heads? I met someone over the weekend that stated how they caught a bunch of large gills out of Lino Lakes in MN that had protruding heads, but he had no pics to show.
In Cichlid terms, protruding heads are called Nuchal Humps or in the flowerhorn community, they call them Kok. As a New World Cichlid enthusiast, I just really love breeding and raising cichlids with protruding heads.
Curious if anyone knows how gills can grow the protruding head and if this is seen often.
