The Crested Horn Shark is less common than the Port Jackson Shark.

More Info


Endemic to eastern Australia, from about Cape Moreton, southern Queensland, to at least Eden, southern New South Wales.

Crested Hornsharks are nocturnal and inhabit rocky reefs with large macroalgae, and nearby sandy and seagrass areas in depths to 93 m. The species is more common in the warmer parts of its range, and may prefer deeper reefs.


To 1.5 m TL



Crested Hornsharks are nocturnal and have a similar diet to the Port Jackson Shark - feeding on a range of bottom-living invertebrates, including echinoderms (especially the sea urchins Centrostephanus rodgersii and Heliocardis erythrogramma) crabs, molluscs and small fishes, using their large rear molars to crush their prey.

The jaw teeth range from small and pointed at the front, to wide, molar-like teeth at the rear of the jaw used for crushing hard-shelled prey items.


Very little is known of the biology and life history of Crested Hornsharks in the wild. Females mature at about 70 cm TL and males from about 54 cm TL. During late winter, females lay spiral-shaped egg cases (11 cm long) attached to sponges and algae by the very long tendrils (up to 2 metres long). The young reportedly hatch at 17-22 cm TL after 8-9 months. The egg cases are thought to be laid in deeper water than those of the Port Jackson Shark.


Crested Hornsharks are not targeted in commercial fisheries and, unlike Port Jackson Sharks, are not taken as often as commercial bycatch or by recreational fishers.


IUCN Red List: Least Concern

EPBC Act 1999: Not listed


Similar Species

Differs from the Port Jackson Shark, Heterodontus portusjacksoniin having more prominent ridges above the eyes and in lacking harness-like markings on the body.


The specific name is from the Latin galeatus (= helmeted), in reference to the large ridges above the eyes.
