Common name: Aeolid Nudibranchs

Facelinidae, commonly known as Aeolid Nudibranchs, are a family of sea slugs characterized by their colorful and often ornate bodies. They are a popular subject for underwater photographers and a fascinating addition to the reef aquarium, albeit not common. They possess cerata, which are finger-like appendages on their back used for respiration and sometimes for defense, as they can store nematocysts from their prey, such as hydroids. Hobbyists should note that they require specific diets, often feeding exclusively on certain types of soft corals, hydroids, or anemones, making them challenging to keep in captivity.
