Sea slug species Elysia chlorotica feeding on Vaucheria litorea, a yellow-green algae. E. chlorotica sequesters chloroplasts from the algae into specialized cells lining the digestive diverticulum, and the chloroplasts are photosynthetically functional for 9 to 11 months. Nuclear-encoded, algal chloroplast genes necessary to the function of the sequestered chloroplasts have been horizontally transferred and integrated into the slug genome. (Date of Image: 2009)
Nudibranchs are SO COOL.
They poop poison if they don't ingest it as defense. They dress up as poisonous critters.
And many people don't even know they exist.
