Speaker: Ariel Camp
Most of the over 30,000 species of fishes rely on suction to capture their food: rapidly opening the mouth so the surrounding water—and food—is sucked inside. However, this fast and forceful feeding behaviour requires substantial power, possibly more than the feeding muscle of the head can generate. Alternatively, power could also be generated by the large muscles of the body. Ariel’s research examines how the body muscles and skeleton can contribute to feeding, and how this role may have shaped the evolution of both body morphology and feeding behaviours. To do this, she combines X-ray imaging with 3D computer animation to visualize muscle and bone motion during natural feeding behaviours in fish. This seminar will present her work on the role of the body muscles in powering suction feeding, and in acting like a neck to transfer motion between the head and body.
