White-and-Orange-tipped Nudibranch    Janolus fuscus



This is one of the more beautiful nudibranchs.  The white and orange color set against the gray background is subtle but appealing.  It is similar in color to the Opalescent Nudibranch, but is smaller and its rhinophores (sensory organs) are covered by the plumes.  It grows up to 1 inch.


This species ranges from Japan to Alaska and south to central California.  It inhabits the intertidal zone and deeper to 100 ft.  It feeds on colonial animals called bryozoa.
