Barhead Damsel

Neoglyphidodon thoracotaeniatus

The Barhead Damsel is a damselfish species found primarily in the Indo-Pacific region, with its range extending from Indonesia to the Solomon Islands, including Australia, Vietnam, the Philippines, and Papua New Guinea. This species inhabits coral-rich areas of outer reef slopes, typically at depths ranging from 10 to 45 meters. Adult Barhead Damsels can reach a maximum length of 13.5 centimeters. They exhibit distinct coloration changes as they mature; adults are predominantly black with a white area extending from the eye to the pectoral fin, and they display three vertical dark bands on their front. Juveniles, on the other hand, are yellow with a dark spot around the dorsal fin, surrounded by turquoise lines extending to the eyes. Barhead Damsels are diurnal and primarily feed on plankton. Juveniles tend to stay close to the substrate, while adults swim higher above the reef to feed on drifting zooplankton. During breeding, they exhibit distinct pairing, with females laying demersal eggs that adhere to the substrate. Males take on the role of guarding and aerating the eggs until they hatch. Divers encountering the Barhead Damsel may observe them in small groups, actively swimming around coral reefs. They are harmless to humans and are also found in the aquarium trade. According to the IUCN, the Barhead Damsel is classified as Least Concern.
