Sea slugs are poisonous mollusks with an efficient defence system; they are characterized by having a non-segmented, transparent body with the ability to emit light. They breathe through gills located in different areas of their bodies; they have two sensory organs in the shape of a horn located on the head; their diet is carnivorous since they feed on other invertebrates.
