How does a catfish survive?

Catfish survive by utilizing their keen sense of smell and taste to locate food in murky waters where visibility is low. They are bottom feeders, primarily consuming aquatic insects, algae, and small fish. Their whisker-like barbels help them navigate and detect food, while their ability to breathe air allows them to thrive in low-oxygen environments. Additionally, their adaptable nature enables them to inhabit a variety of freshwater and saltwater ecosystems.
