Aeolidia
Aeolidia is a genus of sea slugs, specifically nudibranchs, belonging to the family Aeolidiidae. They are known for their striking beauty and intriguing feeding habits. Commonly called “aeolids”, they are easily recognized by their cerata, finger-like projections along their bodies, which are used for breathing and defense.
Common Names
Aeolidia species are commonly referred to as "aeolids", "sea slugs", and "nudibranchs". Some species have specific common names, such as the "green sea slug" for Aeolidia papillosa.
Characteristics
Aeolidia species share several characteristics, including:
- Cerata: Long, slender projections along the dorsal surface that contain digestive diverticula, aiding in respiration and digestion.
- Rhinophores: Sensory organs located on the head, used to detect chemical cues in the environment.
- Oral tentacles: Short, retractable tentacles near the mouth, used for capturing prey.
- Brightly colored bodies: Often displaying vibrant colors, which serve as a warning to potential predators about their toxicity.
- Carnivorous: They feed primarily on anemones and other cnidarians, extracting nematocysts from their prey for their own defense.
Environment
Aeolidia species are found in a variety of marine environments, typically on rocky shores, tide pools, and in shallow waters. Their distribution spans the Atlantic, Pacific, and Indian Oceans.
