About the Cover
COVER: Side and top views of a juvenile mako shark (Isurus oxyrinchus) swimming in the working section of the 3000 l variable-speed water tunnel used in the thermoregulation investigations of the Graham laboratory at Scripps Institution of Oceanography. Temperature recording devices were implanted into the red and white muscle and the stomach, and data were recorded while the shark was subjected to rapid changes in ambient water temperature. The graph shows temperature recordings from red and white muscle and stomach throughout an experimental cycle. Heat transfer coefficients calculated from tissue temperature data suggest that makos have the capacity to control red muscle heat balance physiologically (see Bernal, Sepulveda and Graham, pp. 4043-4054.
