flatheads

Bottom-dwelling Australian fish

Flatheads are catfish of the family Pylodictidae, named for their distinctively flattened heads.

Native to North American rivers, they're popular game fish prized for their size and taste: We caught a thirty-pound flathead in the Mississippi.

Flathead also refers to a type of engine with valves in the cylinder block rather than the head, or informally to flathead screws and screwdrivers with straight, slotted tips.
