More Info


Distribution

Endemic to eastern Australia from off Fraser Island, Queensland, to at least Forster, and perhaps as far south as Ulladulla, New South Wales, and at Lord Howe Island in the Tasman Sea. 

Inhabit reefs in association with gorgonian corals, black corals, algae or sponges.

Features

Dorsal fin 16-20; Anal fin 2-3; Pectoral fin 10-13; Trunk rings 14; Tail rings 31-36.

Head length 9.6-14.7 in SL; short snout, snout length 3.0-4.4 in head length; snout depth 1.8-3.1 in snout length; median dorsal snout ridge continuous, elevated, the margin denticulate to spinulose posteriorly; eye large. Pectoral fin base low to clearly elevated with entire to minutely serrate margins.

Size

To 120 mm SL

Colour

Pale to brown or black with 10-11 irregular, diffuse, pale or dark bands on sides and dorsal surface of body, and indications of dark bars on ventral surface of the trunk rings; snout tip often pale in dark specimens.

Feeding

Preys on small crustaceans.

Biology

Males brood the pear-shaped eggs embedded in spongy epithelial tissue under the tail. The smallest pregnant male found measured 33.7 cm TL. Males carry between 29 to 120 eggs, and oxygen is supplied to the developing embryos via capillaries in the epithelial tissue. 

Fisheries

Taken as bycatch in commercial trawl fisheries, especially in prawn trawls. Trawled individuals may be exported for sale in the Traditional Chinese Medicine Industry.

Conservation

Australian Government Legislation: Marine listed under the Environment Protection and Biodiversity Conservation Act 1999.

IUCN Red List: Data Deficient

Remarks

.

Similar Species

H. dunckeri is most similar to H. boothae but has lower numbers of tail rings (31-36 versus 37-42) and attains a smaller size (120 mm SL versus at least 165 mm in H. boothae).
