Specifically, as hypothesized, temperature affected the heart rate of Daphnia. It was noticed that the Daphnia’s heart rate increased at higher temperatures (close to 34°C) and decreased at lower temperatures (close to 5°C). Since Daphnia are ectothermic, their body ... Web8 May 2024 · Most fish are classified as ectotherms, i.e. their metabolic heat production, and retaining mechanisms are insufficient to provide body warming [ 1 ].
