Relative amounts, as percentage of sum (mean ± sd), of fatty acids in heart tissue total lipids of sea lamprey individuals analysed.

<p>SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids. Cases in which the relative amounts of a fatty acid are significantly different (<i>P</i>< 0.001) among the groups are marked with signs: *a: significantly different from group 1; *b: significantly different from group 2; *c significantly different from group 3. Fatty acids C6:0 and C8:0 are not presented because were not detected in each one of the three groups.
