Pink Salmon (Oncorhynchus gorbuscha)aka Humpies
Apparently, the term arose with Ray Troll
but I first saw it as a story in the above.
It was a phrase that stuck with me.
This fish has the most exaggerated hump I have ever seen. If it is real and not AI it is something. The hump serves as a means of handling rapid stream flows in the west. Something about the fluid dynamics of water and the shape help the fish.
