In fishes, the abducting hyoid bars push the suspensoria outwards. This force transmission is generally assumed to be important during fast suction feeding (strenuous activity). In Astatotilapia elegans the hyoid symphysis can best be modelled as an oblique hinge. The relevance of this hinge morphology on the force transmission has been studied by means of a three-dimensional (3D) model simulating the displacements of the hyoid-suspensorial system. It appears that the transmission force factor… CONTINUE READING
