In Which A Sea Slug Goes Green

Its kleptomania we knew before,
Elysia chlorotica's, that slug's,
Like other ocean dwellers -- only more
Is going on than just some bugs
Kidnapped and put to work within its gut!
It keeps the chloroplasts it eats intact
And making chlorophyll no matter what.
So like a plant -- and this is no mean act --
It feeds on sunlight as it swims along.
So while it still likes algae for a meal
Its need to do so isn't very strong
As long as there is light it needn't steal
Its energy from other life, although
It still does need to feed somewhat to grow.
