Pilgrim Hervia

The pilgrim hervia is small aeolid sea slug, its average size is between 3 to 5 cm. The body is thin and slender, with a long sharply pointed tail. Its body coloration is milky white with 8 to 10 clusters of dorsal cerata which can be bright red, purple, brown or blue, with the tips coloured in luminescent blue. Those cerata act like gills, and each one contains a terminal outgrowth of the digestive gland, a diverticulum. The head, which is the same colour as the body, has a pair of bright orange rhinophores, and with two whitish long buccal tentacles, which look like like horns.
