Harlequin Shrimp

Harlequin Shrimp (Hymenocera picta) is the only known species of the Hymenocera geuns in the Palaemonidae family. But some groups claim that the species should be separated into two sub-species, Hymenocera picta & Hymenocera elegans, as they have different colourations and live in different regions. They feed exclusively on the legs of starfish, unless they're desparate and may feed on urchins.
