Trimma unisquamis (Gosline, 1959)
This tiny goby attains only about 1 in. and lives under ledges and in caves. Rarely seen or photographed, it occurs from Hawaii to the Cocos Keeling Islands in the Eastern Indian Ocean. The photo above (a still extracted from HD video) was taken by Rob Whitton at Pupukea, O`ahu, at a depth of 20-30 ft. More information on this species can be found in Reef and Shore Fishes of the Hawaiian Islands by Dr. John E. Randall.
