More Info


Distribution

Known from the Southwest Pacific - eastern Australlia, Lord Howe and Norfolk Islands, Elizabeth and Middleton Reefs, and New Zealand, including the Kermadec Islands.

The Luculent Wrasse inhabits coastal and offshore reefs and islands in depths of 8 to at least 50 m. The species is very common at Lord Howe Island.

Feeding

 Carnivore - feeds on benthic invertebrates such as crabs and other small crustaceans.

Biology

The species is a protogynous hermaphrodite with females changing sex into males. In New Zealand, individuals mature after one year and females spawn pelagic eggs from March to October.

Remarks

Juveniles are known to clean parasites from other fishes.

Similar Species

Juvenile Luculent Wrasse are somewhat similar to Gunter's Wrasse, Pseudolabrus guentheriwhich lacks the black markings on the upper rear of the body.

Etymology

The specific name luculentus is from the Latin word for 'splendid', apparently in reference to the bright colours of this species.
