Bornella hermanni Angas, 1864

Members of the genus Bornella display a wide variety of colors and gill shape, but they can also be problematic to ID. Note the four undescribed species in Indo-Pacific Nudibranchs and Sea Slugs. Jim's critter shown above while appearing similar to Bornella stellifer , is definitely B. hermanni because the papillae on the rhinophoral sheaths are subdivided. If we could see the entire animal, we would note that it also has only three pairs of gill processes. This species is also known from The Indian Ocean at Christmas Island to Australia, Malaysia, Korea and Japan. One of the larger Bornella species, it reaches 50 mm in length.
