Those who don’t believe in aliens simply haven’t gone diving yet. Hehe ;) A nudibranch photographed just off the coast at Tulamben, Bali, Indonesia.
Nudibranches are a type of soft-bodied mollusc. Often mistaken for a form of sea slug, they are FASCINATING creatures that come in all shapes and colours. The two stalks are its rhinophores and indicate where the head is. The little “pom pom” at the back is its gills.
