  • Nudibranchs are commonly referred to as sea slugs. Although this is true, not all sea slugs are nudibranchs.
  • Nudibranchs obtain their stunning colors as a result of the colorful food they eat. Due to each species being extremely picky eaters they will generally only consume one type of food leading to a plethora of color variations over the 3000+ species.
  • Some nudibranchs such as the “blue dragon” are capable of creating their own food through photosynthesis.
  • Following the Darwinian principle of natural selection or “survival of the fittest” some nudibranchs are known to be cannibalistic, generally eating the smaller of its species.
