Discussion
Tetraplodon pallidus and T. paradoxus often grow intermixed and can be distinguished by several characters (W. C. Steere 1977b). Tetraplodon pallidus has a large operculum that falls off exposing a broad, square-shaped mouth and well-developed, reflexed teeth, and its distal laminal cell walls are thin.
