Sea slug species survives without food by retaining chloroplasts from algae
Published in 27/9/2017
A study published in the journal Scientific Reports (http://www.nature.com/articles/s41598-017-08002-0) by researchers Paulo Cartaxana and Sónia Cruz (DBio and CESAM), in co-authoring with the University of Copenhagen, shows that during periods of food shortage the photosynthesis of the cleptoplasts is important for the survival of Elysia viridis, a species of sea slug abundant on the Portuguese coast.
A restricted group of sea slugs is able to digest the macroalgae it feeds while integrating chloroplasts into its own cells. The process is called kyptoplasty (from the Greek "kleptein" - steal) and the stolen chloroplasts are called "kleptoplasts".
