Outline of Final Research Achievements

Tunas and some sharks are known to maintain elevated body temperature by using heat generated by muscle constriction. However, little is known about the ecological significance of elevated body temperature in fishes. In this study, I attached electronic tags to a variety of sharks to record their swimming behavior under natural conditions. I found that the species with elevated body temperature swim faster and migrate further in an annual cycle, as compared to the species without elevated body temperature.
