Nudibranchs are gastropod mollusks which live in the oceans worldwide from the polar regions to the tropics.  The slugs live in virtually all depths and various species range from the shallow intertidal surf to  depths of more than over 700m.  Although the majority of nudibranchs are benthic creatures which crawl along the seafloor, some prefer other lives and float upside down under the oceans surface or swim in the water column.

Nudibranchs lose their vestigial shell during a larval phase.  To protect themselves they rely on toxins or unpleasant tasting chemicals which are advertised with extremely vivid colors.  In order to enliven the gray winter months, here is a little parade of lovely nudibranchs.  Enjoy!
