Annotation	As a first approximation, whole-body metabolic rate can be considered as the sum of metabolic rates of constituent cells. Yet, among several current explanations of metabolic rate scaling, only two explicitly invoke cell architecture of organisms: (1) the Metabolic Theory of Ecology, which predicts size invariance of metabolically active cells, such as erythrocytes and (2) the cell metabolism hypothesis postulating partial dependence of metabolic scaling on the cell size (CS), which is mediated by nucleus / genome size variation. 2. Here, we tested (1) and (2) by comparing standard metabolic rate (SMR), erythrocyte size (used as a proxy of CS) and nucleus size (NS) between diploid and triploid individuals of a small fish (body mass of c. 3 g) belonging to the Cobitis taenia hybrid complex. 3. We demonstrated a positive correlation of CS with genome/nucleus size and an inverse relationship between those traits and SMR.
