...-like colonies also exhibited larger medusae and a greater amount of gastrovascular flow to the peripheral stolons. To assess differences in the metabolic capacity underlying this variaton in flow, the redox state of the polyp epitheliomuscular cells was measured using the fluorescence of NAD(P)H...
