Biology     Glossary (e.g. epibenthic)

Most abundant in clear waters around coral reefs, occasionally forming schools. Feeds on clupeoids (Harengula, Jenkinsia and Opisthonema) and atherinids (Allanetta [= Craterocephalus), squids and shrimps. Good food and game fish (Ref. 5521). Utilized fresh, smoked and frozen; consumed pan-fried, broiled and baked (Ref. 9987). Sometimes called the "Painted Mackerel" (Ref. 13442).

IUCN Red List Status (Ref. 115185)
