Abstract
    In Pomatoschistus the dorsal fibres of the A-omega-section of the musculus adductor mandibulae-complex insert on the tendon of the A3 section. Three hypotheses are postulated concerning the mechanical implication of this construction during co-contraction of both muscle parts. These are tested for P. lozanoi by means of a mathematical statical bite model. Most likely, this adductor configuration enhances the overall bite performance within the spatial constraints of the gobiid head.
