Largemouth and smallmouth bass are both popular among anglers, but they have some differences. Largemouth bass are typically larger, with a distinctive wide jaw that extends past the eye. They prefer warmer, vegetated waters. Smallmouth bass have a more streamlined body and thrive in cooler, clearer waters with rocky bottoms. Do you have a preference between the two, or are you planning a fishing trip where you're hoping to catch one?
