Etymology: Paracaesio: Greek, para = the side of + Latin, caesium = bluish grey (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 5 - 250 m (Ref. 86942). Tropical; 35°N - 35°S, 37°E - 169°W (Ref. 55)
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).

Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 5484)
Adults occur over rocky bottoms, sometimes forming large schools. They feed largely on zooplankton (Ref. 30573). Marketed fresh or frozen.
