Green sea slug Elysia chlorotica
ingests Vaucheria litorea
cells, extracts chloroplasts and transfers them into its own cells, then
manufactures chlorophyll, photosynthesizes, and survives on autotrophy alone.
"It is the first known molecular evidence for active transcription and
translation of algal chloroplast genes in an animal host" (Mujer et al. 1996). Video is online. Mujer, C., D.L. Andrews, J.R. Manhart, S.K. Pierce, and M.E. Rumpho
1996. Chloroplast genes are expressed during intracellular symbiotic
association of Vaucheria litorea plastids with the sea
slug Elysia chlorotica.
