Rock Bass

Rock Bass in Kentucky are thick-bodied sunfish distinguished by their large mouths, bright red eyes, and five to six anal fin spines - a key identifier separating them from other sunfish species that have only three.

They display dark olive coloration with rows of brown-black spots along their sides and can rapidly change color to match their surroundings for camouflage.
