Blackback Wrasse

Interesting Info

• The Blackback Wrasse is widely distributed along the east coast of Australia. They can be found in various regions throughout the Coral Sea, including the Great Barrier Reef in Queensland and northern New South Wales.
• They are characterised by their distinct coloration and pattern. Juveniles and females have a vibrant yellow or orange body with black markings on their backs, giving them their common name. As they transition into males, their coloration changes to a deep blue or green body with a bright yellow head and black markings.
• Blackback Wrasse are omnivorous, feeding on a diverse diet that includes small invertebrates, algae, and small fish. Their foraging behaviour often involves picking at the substrate, searching for prey items.
• Like many wrasses, Blackback Wrasse possess sharp teeth that are well-suited for capturing and consuming their prey. They have a protrusible jaw, allowing them to extend their mouth to snatch small, elusive prey items.
• These wrasses have a complex social structure, often forming harems consisting of one dominant male and several females. The male defends his territory and mates with the females within his harem.
• Breeding season for Blackback Wrasse typically occurs during the warmer months, particularly from spring to early summer. They engage in elaborate courtship rituals, where the males display vibrant colours and patterns to attract females.
• Their estimated lifespan is between 10 – 15 years.
