The comparative feeding mechanism of Gadidae and Macrouridae. II. Mechanics of the feeding action.
Several aspects of the mechanics of the feeding action from some Gadid and Macrourid species have been studied. From 3 Gadid species (G. callarias, P. virens, M. tricirrata) fails of pressures during feeding have been recorded. Calculations based on the dimensions and architecture of the muscles of the different biomechanical units have been made. It seems that the most of them have to exert their maximum isometric forces to compensate the moments due to the actions of the fails of pressures against the different orobranchial cavity walls. For the Macrourid species, a estimate of the fail of pressure is made supposing a similar moments equilibrium to that of Gadids.
