Pseudamiops diaphanes Randall, 1998
This small cardinalfish is transparent except for the vertebral column and inner organs. It is seen at night, generally higher above the bottom than in the photo. Although it is found most often in caves, the specimen pictured was photographed over coral on a moonless night. Although not uncommon, it is seldom noticed due to its small size and nocturnal habits. To about 1.5 in. Endemic to Hawai`i. Photo: Hönaunau, Hawai`i. 20 ft. (night)
