“There are times when it will go so wrong that you will
barely be alive, and times when you realise that being barely alive, on
your own terms, is better than living a bloated half-life on someone
else’s terms.”

— Jeanette Winterson

The Elysia chlorotica, more commonly known as the Eastern Emerald
Elysia, is a species of green sea slug that is found along the east
coast of the United States. The juvenile sea slugs feed on intertidal
algae but instead of digesting the entire cell contents, it retains only
the algal chloroplasts by storing them in their extensive digestive
system. Over time, these chloroplasts are incorporated into the slug’s
cells and the slug is able to undergo photosynthesis as a means of
obtaining energy.
