Nudibranches are a group of marine gastropod molluscs. These animals have soft bodies and most of them lack an external protective shell. Their secondary gills are exposed outside, as reflected by their latin-greek name “nudibranch” meaning “nuce/naked gills”. Nudibranchs possess fantastic coloration and color patterns, with striking forms. To protect themselves from predators many developed toxic or bad tasting glands in the skin, and their bright colours warn predators of their horrible taste. They are slow moving bottom dwellers. There are over 3000 species worldwide.
