Working mainly with fishes, this laboratory examines the origin, functional bases, and evolution of specializations related to high performance swimming and for life on the edge. Ongoing projects include elucidation of the mechanisms involved in locomotion and the exaptations for endothermy present in the bonitos and tunas (family Scombridae), the nature and degree of evolutionary convergence in the capacities of scombrids and lamnid sharks for high performance swimming, the physiological factors regulating elasmobranch heart function, and the origin of the suite of specializations of mudskippers for amphibious life.
