Nudibranch

 
  The sun is now low in the sky, and a colorful collection of nudibranches (nud-i-branch) are grabbing a late afternoon bite.  Unlike thier drab, land-based couisins, nudibranches brighten up the reef with a kaleidoscope of patterns.  Most nudibranches feed during the day and rest at night.  Belive it or not, nudibranches lay eggs!  Most lay them in a long, coiled ribbon,and the eggs are protected from predators and bacteria by a jellylike substance that joins the eggs.  Nudibranches are solitary animals, but can sometimes be found in small groups.  Nudibranches breathe through external gills.  Nudibranches are carnivores meaning that they eat animals, not plants.  They love to munch on sponges or soft corals, and different types are picky about which food they will eat.Many nudibranches are smaller than your middle finger.Nudibranches are also called sea slugs.
