That's a big ol' gill on top.
I don't recognize the bottom specifically but I reckon they vary from region to region.
We get what we call "pumpkinseeds" up here that fight harder and are generally heavier for the same length than gills.
We get "warmouth" too which look like a mix btw a gill and a "seed" but with a bigger mouth similar to a speck (crappie).
That could just be a hybrid of your local strains.
Some species breed together and some don't up here...I reckon it's the same down there.
Helluva good time regardless!
