basibranchial teeth

epibranchial organ

branchiostegal membrane

The membrane, sometimes referred to as the gill membrane, connecting the branchiostegal rays and enclosing the ventral portion of the branchial cavity. Normally extended when the opercle of a fish is open, sealing the branchial cavity and creating a vacuum in the mouth, and also used during threat, courtship and other communicative behaviours in many species.

pharyngeal teeth

Opposing patches of teeth located on the upper and lower portions of the branchial arches in many fishes, e.g., cyprinids. Variable in structure and to an extent, function.

visceral arch

One of the bony or cartilaginous arches situated on either side of the pharynx that form the branchial arches and lower jaw.
