Description
Dorsal spines (total): 10-11; Dorsal soft rays (total): 14-16; Anal spines: 3; Anal soft rays: 11-13; Pectoral fin rays: 22-24; Lateral line scales: 68-76; Cheek scales: 4-6; Predorsal rays: 24-32; Scaled dorsal and anal fins. Upper peduncular scale rows: 12-14 (usually: 12-13); Lower peduncular scale rows: 15-17 (usually: 16-17). Post maxillary processes: 2; Posterior end of maxilla tapered. The process on ventrolateral surface of basioccipital for attachment of Baudelot's ligament not extending beyond a horizontal with condyle's rim. Head length: 3.0-3.7 in SL; Body depth: 3.4-4.6 in SL. Eye diameter: 3.1-5.5 in HL; Pectoral fin length: 1.0-1.5 in HL. Body fusiform, greatest depth through base of spiny dorsal fin; Head bluntly pointed, with a slight concavity at tip of snout; Caudal peduncle slender, dorsal and ventral profiles about evenly curved; Interorbital space convex; Lateral line complete, a little above midaxis of body anteriorly, but along it on caudal peduncle; Body covered with weekly ctenoid scales, scarcely or not rough to the touch; Scales absent on snout, around orbit, mouth, lower jaws, gill membranes, and lower part of preopercle; Caudal fin scaled about two-thirds of the way out its length; Basal parts of pectoral, dorsal, and anal fins scaled; Origin of dorsal tin a trifle behind a vertical line through pelvic insertion; Pectoral fins extend only a trifle past tips of pelvics; Last rays of dorsal and anal fins not notably elongate; Tips of caudal fin lobes pointed; Pectoral fins pointed; Margin of spiny dorsal without an emargination between spiny and soft parts; Gill rakers slender; Teeth small, conical, in a single row in both jaws, none on vomer or on palatines; Symphysis of premaxillary edentulous; Dentary with elevated ramus at side; Premaxillaries excessively protractile, the ascending median processes reaching a little past front of orbits into interorbital space; Preopercular edge membranous, expanded at lower corner to form a small lobe; Opercular edge membranous, with one thin flat spine; Nostrils separated with a wide dermal isthmus between each pair; Anus in front of anal origin a distance equal to diameter of orbit; Sides of premaxillaries with two short processes. Max. length: 35.0 cm TL. Depth range: 1 - 30 m, usually: 1 - 10 m.

Color
Body pale blue to greenish dorsally, white below, with 2 thin yellow stripes: lower stripe (~1 scale wide) from behind supratemporal membrane and covering lateral line to caudal fin base, and above lateral line on peduncle; Upper stripe (1-2 scales wide) below dorsal fin to peduncle; Fins mostly white to pinkish; Dorsal fin dusky distally; Pectoral-fin axil with black blotch; Caudal-fin tips black.

Etymology
Pterocaesio: from Greek, pteron = wing, fin + from Latin, caesius = blue-grey or bluish-grey.
marri: in honor of John C. Marr, U.S. Fish and Wildlife Service, in charge of the commercial fishing operations at Bikini Atoll (type locality) in the Marshall Islands, South Pacific Ocean.
Original description: Pterocaesio marri Schultz, 1953 - Type locality: Lagoon 1/4 mile off Amen Island Bikini Atoll, Marshall Islands, western Pacific.
Distribution
Indo-West Pacific: KwaZulu-Natal (South Africa), East Africa, Socotra (Yemen), Seychelles, Comoros, Madagascar and western Mascarenes (La Réunion, Mauritius) east to Marshall Islands and Marquesas Islands (French Polynesia), north to southern Sea of Japan, Pacific coast of southern Japan and Ogasawara Islands (Japan), south to northern Australia and Tonga.
Biology
Ranges widely around coral reefs and appears to prefer clear waters of oceanic islands or reefs far from large land masses. Feeds on zooplankton in midwater aggregations. Oviparous, with numerous, small pelagic eggs. Also caught by drive-in nets. Used as tuna baitfish.
Similar species
Pterocaesio digramma (Bleeker, 1864) - Reported from New Caledonia - Link to the species (here) - Body blue to greenish dorsally, white ventrally. With two thin yellow to orange lines; Lower line mostly just below lateral line. Black tips on caudal fin.
