More Info


Distribution

Carnarvon, Western Australia, to Woy Woy, New South Wales. Elsewhere the species occurs in the tropical, Indo-west Pacific, from western Persian Gulf (Kuwait, Saudi Arabia), north central Indian Ocean, and eastward to Japan and Australia.


Found in the lower reaches of streams and rivers, in estuarine seagrass beds and other shallow inshore habitats.

Features

Dorsal fin 25-30; Pectoral fin 15-18 (usually 17); Trunk rings 14-16; Total rings 36-41.

Head length 6.9-10.3 in SL; snout moderately long, 1.8-2.1 in head length; snout depth 3.6-5.7 in snout length; median dorsal snout ridge low; keels typically present on some or most scutella; superior trunk and tail ridges discontinuous; inferior trunk and tail ridges continuous; lateral trunk ridge straight and not deflected ventrally near the anal ring.

Dorsal fin usually originates on the  2nd-3rd tail ring, fin base not elevated.

Size

To 180 mm TL.

Colour

Generally tan, greenish or brown with numerous dark-edged white spots on sides and about 10 narrow pale bars across the back; sides of tail rings usually with a semicircular pale blotch on or above the inferior ridge.

Feeding

Feeds on small planktonic crustaceans.

Biology

Males incubate the eggs in a brood pouch under the tail. the pouch has protective plates and an everted pouch closure. Males may begin brooding at 100 mm SL. Males and females form monogamous pairs.

Brood pouch eggs are oval and crowded in up to 10-11 transverse rows (typically in a single layer) across the upper part of pouch folds and dorsum of the pouch; not in a continuous gelatinous matrix but covered by protective folds which meet or overlap on ventral midline.

Fisheries

The Bellybar Pipefish may be collected for sale in the aquarium industry.

Conservation

Marine listed under the Environment Protection and Biodiversity Conservation Act 1999 and subject to the export controls of the Commonwealth Wildlife Protection (Regulation of Exports and Imports) Act 1982.

Remarks

Specimens from different geographic regions vary somewhat in morphology and further investigation may reveal that this variation represents a species complex.

Etymology

Hippichthys is from the Greek ippos, meaning horse and ichthys for fish.
