  1. Fatty acid values are given in mean mole% ± S.D. Only fatty acids that showed a proportion of over 1 mole% in at least one of the animals were included in the table (n = 32). Values of total saturated (total SFA), monounsaturated (total MUFA), polyunsaturated (total PUFA), unknown (totally unknown) fatty acids, and ratios are shown as well (in bold) and were calculated from the total fatty acids (n = 98) identified in the lung. As there were no significant differences in the fatty acid composition of animals positive/negative to fat emboli, all animals from these two species were considered in the table (Z. cavirostris n = 5 and P. macrocephalus n = 4).
