Redear Sunfish

Redear Sunfish are an introduced (non-native) species in Delaware, commonly known as "Shellcrackers" due to their specialized diet of freshwater clams, mussels, and snails. They are one of Delaware's larger and least colorful sunfish.
Also known as Shellcrackers
Light green to brown backs, grey to olive green sides, and yellowish to cream-colored chests. Their sides display brown spotting in a mottled, checkered pattern, and may or may not have vertical bars like bluegill.
Males have distinctive black gill flaps lined with red (hence the name), which turn bright red during spawning, while females have orange-lined gill flaps that may be faint or absent in larger fish.
They grow larger than most sunfish, commonly reaching 8-10 inches in Delaware waters.
