DNA amplification experiments on Elysia chlorotica adults and eggs using Vaucheria litorea derived primers revealed the presence of psbO, an algal nuclear gene. [11] These results were likely an artefact, as most recent results based on transcriptomic analysis [ 12 ] and sequencing of genomic DNA from the slug's eggs [ 13 ] reject the ...
This species of nudibranch shed their eggs in masses around 20 million offspring or more. [3] Egg shape is arranged in a spiral pattern in its own capsule and color ranges from white to pink (See Fig. 1). [17] Egg composition arranges in two equivalent layers which can be detected by electron micrographs. [18]
