Arranging differentially abundant lipids between Heliocidaris erythrogramma (red) and Heliocidaris tuberculata (blue) eggs (from Figure 2b) according to lipid class reveals qualitative differences in the energetic composition of oocyte provisioning between lecithotrophic and planktotrophic development. Long-term, low-density diacylglycerol ether lipids comprise many of the differentially abundant lipid molecules in H. erythrogramma eggs relative to H. tuberculata, whereas energetic lipid content in H. tuberculata eggs is dominated by triacylglycerols. Significantly differentially abundant lipids (n) are called as having an FC ≥ 2 and a Tukey’s honest significant difference corrected p ≤ 10%. FC: fold-change; R: hydrocarbon chain
