Morphological components of four functional systems associated with prey capture in percomorph fishes. Landmarks: (1) anteriormost extent of premaxilla; (2) anteriormost extent of dentary; (3) point of articulation between the supracleithrum and post-temporal; (4) dorsalmost extent of epaxial, measured dorsal to landmark 3; (5) point of articulation between supracleithrum and post-temporal on opposite side of fish, measured in the frontal plane; (6) posteriormost extent of buccal cavity, measured between landmarks 1 and 3; (7) anteriodorsal extent of maxilla; (8) quadrate-articular jaw joint; (9) insertion of the interopercular-articular ligament; (10) opercular joint; (11) posterioventral extent of interopercule. Bone names: pmx = premaxilla, max = maxilla, art = articular, quad = quadrate, pop = preopercule, iop = interopercule, sop = subopercule, op = opercule, pt = post-temporal, scl = supracleithrum, cl = cleithrum, nc = neurocranium.
