Purple Wrasse

Interesting Info

• The Purple Wrasse, is a temperate reef wrasse found across southern Australia and around New Zealand, favouring rocky reefs and kelp beds in cooler waters.
• In Australia, it occurs from southern New South Wales through Victoria, Tasmania and South Australia.
• Males and females differ in colour: males are dark purple-brown with a yellow-orange band on the pectoral fins, while females are more reddish to brown with mottled patterning.
• Juveniles are generally mottled brown and orange, providing camouflage among kelp fronds and rocky crevices until they mature.
• Like many wrasses, Purple Wrasses are protogynous hermaphrodites, beginning life as females before some transition into dominant males as they grow larger.
• They are strong predators of hard-shelled invertebrates, feeding mainly on crabs, sea urchins, molluscs, and small crustaceans, which they crush with powerful jaws and teeth.
• This feeding behaviour helps regulate populations of sea urchins and crabs, making the species ecologically important for maintaining kelp forest balance.
• Purple Wrasses are diurnal and spend much of the day patrolling rocky reef territories, retreating into crevices at night to rest.
• Spawning occurs in spring and summer. Males establish territories and display to attract females, with eggs released into the water column to drift with currents until hatching.
• They can live for more than 10 years, with older, large males often dominating reef territories.
• Divers and snorkellers often encounter Purple Wrasses in kelp beds, where they are curious and bold compared to smaller wrasses, making them easy to observe.
• They are sometimes caught by recreational fishers in southern Australia and New Zealand, though they are not a primary target species.
• The species name fucicola means “dweller among seaweed,” a direct reference to its strong association with kelp and algal habitats.
