Warmouth
Lepomis gulosus
A heavy-bodied native sunfish of weedy lakes, dark swamps, canals, and slow Florida rivers.
Warmouth tolerate warm, stained, and low-oxygen water better than many sunfish. They favor cover such as aquatic plants, roots, stumps, and undercut banks.
They are ambush predators with a large mouth and sturdy body. Anglers often find them in quiet backwaters and vegetated shoreline zones.
