Luculent Wrasse

Pseudolabrus luculentus

The Luculent Wrasse, also known as the orange wrasse, is a colorful reef fish found in the temperate marine habitats of the Southwest Pacific. It inhabits regions from Australia to New Zealand and the Kermadec Islands, often residing in inshore waters at depths ranging from 10 to 50 meters. Female and juvenile Luculent Wrasses are predominantly orange, adorned with five vertical white bars and yellow markings on their heads. In contrast, males exhibit a red-brown coloration with distinctive black-and-white squares beneath the rays of their dorsal fins. These visual differences make it relatively easy to distinguish between sexes and age groups. Luculent Wrasses are carnivorous, primarily feeding on benthic invertebrates, including small crustaceans. Females and juveniles occasionally engage in cleaning behavior but rely more on benthic feeding. The species is oviparous, forming pairs during the breeding season, with females spawning eggs from March to October. Notably, they are protogynous hermaphrodites, meaning females can change sex to become males as they mature. Divers encountering the Luculent Wrasse may find them to be a common sight, particularly in places like Boat Cove at the Kermadec Islands, where they are the most prevalent fish across the reef. Their population density can reach up to 37 individuals per 500 square meters in shallow waters. The IUCN lists the Luculent Wrasse as Least Concern.
