Spiny Gurnard

Lepidotrigla papilio

The Spiny Gurnard, known scientifically as Lepidotrigla papilio, is a distinctive reef fish endemic to the coastal waters of southern Australia, from central New South Wales to southwestern Western Australia, including Tasmania. Divers can spot this species in temperate marine environments, typically in depths less than 50 meters, although they can be found as deep as 110 meters. Juveniles occasionally inhabit seagrass beds. The Spiny Gurnard is characterized by its large, bony head and specific coloration. It is predominantly red with reddish-brown to dark brown mottling on its dorsal side, while the ventral side is whitish. Notably, the first dorsal fin features a large black spot edged with white, and the pectoral fins have a dark green inner surface with a thin blue band, resembling an eyespot in juveniles. This species is a bottom-dwelling carnivore, feeding on various small invertebrates. Divers encountering this fish may notice its slow-moving behavior as it navigates the sandy and shelly substrates of its habitat. The conservation status of the Spiny Gurnard has not been evaluated by the IUCN, and it poses no threat to humans. It is of no interest to fisheries, making it a unique find for divers exploring the temperate reefs and coastal waters of Australia.
