About this work
Nudibranchs are gastropod mollusks, characterized by their lack of a shell, which earned them the name "sea slug".
Antiopella cristata is a nudibranch found in the North Sea, the North-East Atlantic and the Mediterranean. Its body, with a maximum size of 8 cm, is flat, elongated and hidden by numerous outgrowths, the cerata, whose extremities are pale blue. The colour of these animals varies from milky white to light orange. The main sensory organs of nudibranchs are their rhinophores, which detect chemical particles present in the water, including food, the pheromones of a possible sexual partner, or the presence of certain threats. In these photographs, the rhinophores are clearly visible on the head of this nudibranch. These are lamellate, and their tip is whitish. We can also observe on the head a crest, a caruncle, characteristic of Antiopella cristata.
