Geographic Range [top]

Range Description: Pegasus lancifer is a temperate, inshore endemic species (Paxton et al. 1989) whose extent of occurrence includes the southern coast of Australia between Rottnest Island, Western Australia and Lakes Entrance, Victoria including Tasmania (Palsson and Pietsch 1989, Edgar 1997).

No information is available on the species’ area of occupancy.

Habitat and Ecology [top]

Habitat and Ecology: Habitat
Adult Pegasus lancifer are mainly bottom-dwelling fish that are most often found on sand or mud amongst or near seagrass (Gomon et al. 1994) or near low rubble reef (Kuiter 1996). They occur at a variety of depths from intertidal shallows to ca. 55 m (Gomon et al. 1994).

Behaviour
Pegasus lancifer camouflages itself by rapidly changing colours to match its surroundings and occasionally burrows into the substrate to escape predators. In spring, the species enters sandy bays to breed, sometimes congregating in small numbers. Juveniles are pelagic before taking on the adults’ bottom mode of existence (Kuiter 1985, Gomon et al. 1994). This species is mostly buried during the day, and active at dusk. Males have ornamental patches on the edges of their pectoral fins for displaying to females (Kuiter 1996). Spawning involves the pair swimming upwards together, to several meters from the substrate. They quickly dart back after the release of eggs and sperm, which floats to the surface. These activities have been observed to occur towards dusk on high tides (Kuiter 1993). Seasonal migrations are suggested by the fact that they are trawled with prawns only during certain times of the year (Kuiter 1985). They often crawl over the seabed on their paired fins in search of small crustaceans, worms and molluscs on which they feed (Kuiter 1985, Gomon et al. 1994).

Size
Pegasus lancifer reaches a maximum length of 12 cm (Kuiter 1996).

Threats [top]

Major Threat(s): Presently, the only known threat to this species is direct take as bycatch in bottom trawls, where P. lancifer is trawled with prawns during certain times of the year (Kuiter 1985).

It is also possible that trawling may also exert indirect effects on habitat used by P. lancifer, and that inshore development may affect their distribution, given depth records from 0–56 m.

There is no known trade for this species at the present time but it may enter the traditional medicine trade along with other pegasids in the future (Vincent 1997).
