Etymology: Euleptorhamphus: Greek, eu = good + Greek, leptos = thin + greek, rhamphos = bill, peak (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 1 m (Ref. 58302). Subtropical
Indo-Pacific: Red Sea and East Africa to Hawaii (Ref. 583) and Tonga, north to southern Japan, south to Australia, New Zealand and Kermadec Islands (Ref. 8879). Eastern Pacific: southern California, USA to Ecuador, including the Galapagos Islands (Ref. 2850).

Max length : 53.0 cm TL male/unsexed; (Ref. 55763); common length : 30.0 cm SL male/unsexed; (Ref. 9306)
soft rays: 20 - 25;
Vertebrae: 70 - 75. Body very elongate; lower jaw very prolonged; upper jaw short, triangular, and scaly; teeth present on vomer and tongue; dorsal fin with 22 to 25 rays; anal fin with 22 to 24 rays; pectoral fins long, with 8 or 9 rays; back iridescent blue green; belly silvery (Ref. 55763).
