Also, these sea slugs utilize kleptoplasty—taking chloroplasts from their food and incorporating them into their cells where photosynthesis can be used—which may help them survive until they regrow enough body to function normally, although it is still a mystery how they can survive in this state…

It was observed to take about a week for the sea slugs to grow their new heart and even their entire body in some cases. This species lives in the Indo-Pacific in shallow water where they feed off of algae. Here’s one of the studies for more info: www.sciencedirect.com/science/arti...

Extreme autotomy and whole-body regeneration in photosynthetic sea slugs

Autotomy, the voluntary shedding of a body part, is common to distantly-related animals such as arthropods, gastropods, asteroids, amphibians, and liz…
