While looking at this Elysiid egg mass on Halimeda algae, we noticed a tiny Elysia species crawling down across it. Although this Elysia was clearly too small to have laid the eggs, the presence of white extra-capsular yolk scattered among the small yellowish eggs is enough to show it is from another Elysia. This small one could be a young Elysia pusilla, but the morphology looked wrong, so we are keeping it separate.
