Sea slugs or Nudibranchs are favorites of many divers because of the incredibly striking patterns and brilliant colours. Recent research is making many new and fascinating discoveries about Nudis. Solar powered sea slugs such as the Purple Dragon, store tiny single celled marine plants in their cerrata. They also store chemicals in toxic glands from the sponges things that they eat.
