More Info


Distribution

Bunbury to Shark Bay, Western Australia (and possbily from the Onslow region), and north of Cardwell, Queensland, southwards to Franklin Harbour, South Australia (H. r. ardelio). Inhabits surface waters in bays, estuaries and sheltered coastal waters, often around seagrass beds.

Features

Dorsal fin 14-17; Anal fin 15-19; Pectoral fin 11-12; Caudal fin 15; Pelvic fin 6; Lateral line scales 58.
Body very shallow (10-13% SL), elongate, rectangular in cross section; caudal peduncle narrow.  Head small (22-25% SL), flattened above, triangular in cross section; snout of moderate length; lower jaw produced into an elongate, depressed beak, extending well beyond tip of upper jaw; preorbital bone without posterior branch of preorbital canal; eyes of moderate size (21-26% HL);  mouth small (upper jaw length 21-26% HL), nearly horizontal; teeth tiny, many tricuspidate in large specimens, narrow band in each jaw; 30-36 (usually 31-34) gill rakers on first gill arch.

Scales of moderate size, cycloid, weakly attached, covering body and most of head including at least some of triangular part of upper jaw; lateral line low on side, following ventral profile, lateral-line scales smaller than others on sides.

Dorsal and anal fins small, of similar size and shape, located posteriorly on body opposite each other, anterior rays longest; caudal fin forked, lower lobe slightly larger than upper; pectoral fins of moderate size, arising high on side, reaching about one-fourth of way to dorsal-fin origin; ventral fins small arising slightly closer to anal-fin origin than to opercular edge, reaching far short of anal-fin origin; distance from ventral-fin origin to base of tail about equal to distance from ventral-fin origin to posterior edge of orbit.

Size

Reaches at least 35 cm, including beak.

Colour

Greenish above, silvery white below, with three narrow dark streaks running along foremost portion of back, and a longitudinal silver stripe from opercular edge to base of tail;  tip of beak orange-red; fins yellowish with black spot at base of pectoral.

Feeding

Omnivorous feeding on zooplankton and seagrasses.

Biology

Spawning occurs between July and December.
Eggs are large with adhesive filaments that attach to vegetation.

Remarks

The river garfish has been split into two geographically separated sub-species, the eastern river garfish, Hyporhamphus regularis ardelio and the western river garfish, Hyporhamphus regularis regularis.  The eastern form has a beak that is slightly longer proportionately than that of the western form.
