----------------------
Description
Dorsal spines (total): 9-12; Dorsal soft rays (total): 23-28; Analspines: 3; Analsoft rays: 23-28; Lateral line scales: 60-63; Vertebrae: 31. Body ovoid. Predorsal scales extending forward to nostrils; Scales very small in anterior patch, sharply demarcated from larger posterior scales; Rounded snout; Terminal jaw; Small teeth, conical, mostly uniserial; Deeply forked caudal fin with rounded lobes. Max. length: 23.0 cm SL. Depth range: 20 - 550 m.
Color
Dark horizontal lines laterally.

Psenes: from Greek, psenos, -e, -on = without hair. Reffering to their palate which is smooth and without any teeth. A characteristics of this species.
cyanophrys: from Greek, kyanos = dark blue-green in color + from ancient Greek, ophrûs = eyebrow. Referring to bluish streak above each eye on some specimens.
Original description: Psenes cyanophrys Valenciennes, 1833 - Type locality: New Ireland, Bismarck Archipelago, Papua New Guinea, western Pacific.
Distribution
Circumglobal in tropical through warm temperate seas (including southern Sea of Japan).
Biology
Inhabits the open ocean. Found under floating weeds or debris. Adults were found under large weed-rafts, using the shade as cover. They also form schools. Associated with Sargassum and jellyfish. Feeds mostly on planktonic organisms including copepods, amphipods, fish eggs and larvae, and chaetognaths. Nektonic
