Sea slug
Nudibranch. Nudibranch, or true sea slug, Chromodoris reticulata, on the seabed. The gills (breathing structures) are seen at upper right and the two rhinophores are seen at centre left. The rhinophores are used to sense chemicals in the water. Nudibranchs (meaning naked gills) are sea slugs without a shell or true gills. They are carnivorous, feeding on invertebrates, and may store toxins from their prey for future use. The bright colours of sea slugs warn predators that they are poisonous. This sea slug is found in the tropical Indian and western Pacific oceans.
