marino associati a barriera corallina; distribuzione batimetrica 5 - 250 m (Ref. 86942). Tropical; 35°N - 35°S, 37°E - 169°W (Ref. 55)

Distribuzione Stati | Aree FAO | Ecosystems | Presenze | Point map | Introduzioni | Faunafri

Indo-Pacific: East Africa to the Austral Islands, north to southern Japan, south to southeastern Australia. Paracaesio xanthura, a complex of variable populations, may compose a single or two (or more) species. Paracaesio pedleyi, from Lord Howe Island, Middleton Reef, and eastern Australian waters, is included here with some reservation (Ref. 9821).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 3; Raggi anali molli: 8 - 9. This species is distinguished by the following characters: body relatively deep and laterally compressed, greatest body depth 2.5-2.8 in SL; interorbital region convex; mouth terminal, jaws about equal; anterior end of upper lip without a thick fleshy protrusion; maxilla with or without scales and without longitudinal ridges; teeth in jaws caniniform to villiform; gill rakers of first gill arch 5-11 + 18-20; soft rays of dorsal fin usually 10, in anal fin 8; lateral line scales 70-72; caudal fin forked. Colour bright blue; broad yellow band over most of dorsal half of body, including most of caudal pedincle fin (Ref. 9821, 90102).

Biologia     Glossario (es. epibenthic)

Adults occur over rocky bottoms, sometimes forming large schools. They feed largely on zooplankton (Ref. 30573). Caught mainly with handlines and bottom longlines and marketed fresh or frozen (Ref. 9821).
