Yellow Costasiella- Cutest Nudibranch!

Isn't She Lovely ?? ? But is She a Thief? ?????? ? The yellow costasiella sucks the sap from the Avrainvillea plant, partially digests it, and stores it inside its body. ? ? As it does not fully digests the sap, it uses the plastids of the cells to produce energy via photosynthesis, in a process that is called kleptoplasty. ? ? Derived from the Greek word for thief, "Kleptes," it means this sea slug "steals" the plastids, which is an area in the cell where photosynthesis is conducted. ? ? Awesome video by @oceanvizion?
