Common name: Sacoglossans

Sacoglossa, commonly known as sacoglossans or sap-sucking slugs, is an order of small, often colorful sea slugs. These gastropods are known for their unique feeding habits, as they consume and then retain chloroplasts from algae in a process called kleptoplasty. This allows them to photosynthesize like plants, a rare ability in the animal kingdom. Sacoglossans are fascinating for reefkeepers due to their specialized diets and potential benefits in controlling certain types of algae in the aquarium. However, their specific dietary requirements can make them challenging to keep.
