The mandarin fish (S ynchiropus splendidus) swims in the south-west Pacific Ocean close to Australia, Taiwan, and the Philippines. Its array of color is similar to that of the robes worn by an Imperial Chinese mandarin or bureaucrat. The blue color comes from a cellular pigment that is unique to the species. The mandarin fish is only 6 cm long. It dwells in secluded lagoons and reefs, eating small crustaceans.
