A, schmatic representing the linkages that form the feeding position of dragonfishes and utilization of the occipital-vertebral hinge to create high gape angles. B, head-on view of Malacosteus niger, demonstrating its hypothesized feeding position (sensu Günther & Deckert, 1959). ph, protractor hyoideus.

Schematic representation of variables of the lower-jaw lever system used in model calculations of bite force and jaw-adduction dynamics in four dragonfish species; A, lateral view, B, ventral view. Li, inlever length; Lo, outlever length; Lsym, length of symphyseal membrane; q, muscle-fibre pennation angle
