Flathead catfish are large fish with several names. Depending on the region, flathead catfish are sometimes called mudcats or shovelhead cats.

Some people with the Ozark Mountains dialect call this large fish granny cat. They are North American freshwater catfish and can be found throughout the Great Lakes and northern Mexico.

Appearance and Size

Flathead catfish are unique compared to other catfish. As the name suggests, they have flatter heads than most other catfish species.

Flathead catfish are olive-colored on their sides and dorsum, with a white to yellow underside. Interestingly, the color varies depending on where the flathead catfish live. In clear water, flathead catfish are strongly mottled with dark brown to black color. They have small eyes and a larger protruding lower jaw.

Flathead catfish are the second largest North American catfish. They typically grow between 14 to 15 inches and weigh up to 123 pounds. However, some larger flathead catfish have been found to measure over 61 inches, that’s over 5 feet long!

Diet

These large fish aren’t picky, however, they prefer live prey. Flathead catfish are voracious carnivores consuming live prey like insects, fishes, worms, and crustaceans. Some flathead catfish sometimes eat smaller catfish. They hunt feeling by feeling the vibrations in the water.

To be more specific, flathead catfish eat crayfish, American gizzard shad, channel catfish, green sunfish, and carp.

Predators

Since adult flathead catfish are so large, they have minimal predators. Their most common predators are humans who fish for them commercially and recreationally and other larger catfish. Male flathead catfish are aggressive and protect their nests and eggs. However, it’s more common for young flathead catfish to become prey to larger catfish.
