Description and Size

Flathead catfish are olive, white, and yellow fish. They are olive-colored on their sides and dorsum and white on their undersides. However, flathead catfish vary in coloration. These catfish also have dark, mottled markings on their bodies, which tend to be more noticeable in young flathead catfish in clearer waters.

Flathead catfish are best known for their flat heads and protruding lower jaw. They also have small eyes and anal fins with 14 to 17 rays. Flathead catfish range in size. They are typically between 15 to 45 inches long but can measure up to 69 inches. The largest flathead catfish ever caught weighed 123 pounds.

Distribution and Habitat

So, where can you find flathead catfish? Flathead catfish are native to parts of North America, from the lower Great Lakes region to northern Mexico. Although native to parts of North America, it’s considered an invasive species in some states, including Delaware.

Flathead catfish are solitary animals. They spend most of their time in deep pools of streams, rivers, canals, lakes, and reservoirs. In these pools, the water is typically cloudy or murky and slow. Flathead catfish take shelter under trees or fallen debris.

Diet

Flathead catfish are excellent hunters. Their diet consists of live prey, including other fish species, insects, and crustaceans. Their diet, though, changes depending on their size. Young flathead catfish under 10 inches long mainly eat invertebrates. Flathead catfish aren’t picky. They’ve been recorded consuming other, smaller flathead catfish.

Predators

Adult flathead catfish have few predators. They are so large and fast that no known species frequently attack them other than humans and other flathead catfish. However, young flathead catfish are vulnerable to attacks. Other fish, birds, and turtles eat them.
