The sucker consists of a pre\u2010valvular cavity, formed by a modified lip disc, and is separated from the larger post\u2010valvular buccal cavity by a muscular oral valve. The combination of respiration and suction attachment seems paradoxal, as a properly functioning suction device would need a sucker without leakage (yet inspiration must occur via the sucker), and continuous subambient pressure in the sucker cavity (even during expiratory mouth floor elevation). In the loricariid\n                    <jats:italic>Pterygoplichthys disjunctivus<\/jats:italic>\n                    , the anatomy of the suckermouth structures was examined, and a kinematic analysis was performed to acquire insights into how respiration and attachment are combined. High\u2010speed external and X\u2010ray recordings show that suckermouth attachment influences respiratory parameters such as decreasing excursion amplitudes of mouth floor elements, and the way water enters the mouth via furrows in the lip disc. Respiration, however, continues during attachment and is not blocked. Our data show that the muscular oral valve actively separates the post\u2010valvular buccal cavity from the pre\u2010valvular sucker cavity. Volume changes of this pre\u2010valvular cavity are opposite to those of the post\u2010valvular cavity and assure sucker function even during expiration. These volume changes are caused by movements of the lower lip, the lower jaws, and the oral valve. The lateral inflow furrow openings, controlled by the maxillary barbels, can occur unilaterally. Morphological and kinematic data also show that the opercle is anatomically and functionally decoupled from the gill opening.\n                    <jats:italic>J. Exp.
