Blackspotted Wrasse

Interesting Info

• The Blackspotted Wrasse is endemic to Australia, occurring in southern Queensland, South Australia, and across to south-western Western Australia.
• It is the only species in the genus Austrolabrus, making it a unique representative of this wrasse lineage.
• Adults have a reddish-brown to orange body with distinctive black spots scattered along the sides, giving the species its common name.
• Juveniles are more mottled and camouflaged, often resembling small reef fishes or blending among algae and seagrass.
• Males are slightly larger and more brightly coloured than females, especially during breeding season when their colours intensify.
• The species inhabits shallow coastal reefs, rocky shorelines, and seagrass beds, where it hides among kelp and weed-covered rocks.
• It feeds mainly on small benthic invertebrates, including amphipods, tiny crustaceans, worms, and molluscs, which it nibbles from algae and rubble.
• The Blackspotted Wrasse is diurnal, foraging actively by day and sheltering among kelp holdfasts or rocky crevices at night.
• Spawning occurs in spring and summer, with eggs released into the water column to drift until hatching.
• Like many wrasses, it is a protogynous hermaphrodite, starting life as a female before some transition into males as they grow larger.
• This species is relatively short-lived, with individuals estimated to live about 5–7 years in the wild.
• Predators include larger reef fish such as snapper, as well as cormorants and other seabirds that hunt in shallow kelp zones.
• It is ecologically important as part of temperate reef communities, helping control small invertebrate populations and serving as prey for larger fishes and seabirds.
