Solar Powered Sea Slugs

The Oxford University Press always has interesting articles, with odd little tidbits of information.  For instance here’s one on “crawling leaves” by Sonia Cruz:

‘Crawling leaves’ or ‘solar-powered sea slugs’ are common terms used to name some species of sacoglossan sea slugs capable of performing photosynthesis, a process usually associated with plants. These sea slugs ingest macroalgal tissue and retain undigested functional chloroplasts in special cells of their gut (kleptoplasty). The “stolen” chloroplasts (kleptoplasts) continue to photosynthesize, in some cases up to one year.
