Thiamine pyrophosphate serum concentrations of bottlenose dolphins (Tursiops truncatus) in relation to lactation status. Box plots comparing thiamine pyrophosphate serum concentrations in lactating and non-lactating bottlenose dolphins (Tursiops truncatus). N = 7 for lactating females, N = 47 for non-lactating dolphins. Box plots show the range of the mean 50 % of the data. Within the boxes, the thick line indicates the arithmetic mean. Fifty-four is the number of one dolphin, indicating an outside value
