Biomechanics and Evolution of Fish Feeding
posted December 06th, 2010
Fish feeding biology is a well-established model system for the study of biomechanics, physiology, and comparative diversity. In this lab, we are developing biomechanical models of complex feeding movements in coral reef fishes to test new hypotheses for the mechanism of jaw opening and upper jaw protrusion in fishes. Models include four mechanisms of feeding mechanics in seven labrid fish species (Westneat 1990; 1994), the highlight of which is the spectacular jaw mechanism of the sling-jaw wrasse (Westneat 1991). In addition to proposing novel feeding mechanisms, this research allowed an evolutionary analysis of biomechanics in fishes (Westneat, 1995).
