The Whitebar Damselfish (Plectroglyphidodon leucozonus) is a species within the Perciformes order, belonging to the Pomacentridae family. This tropical, marine, and reef-associated fish exhibits a non-migratory lifestyle and resides at depths ranging from 1 to 6 meters. The species can achieve a maximum length of 12 cm.
Occupying very shallow regions exposed to wave action, adults are typically found in surge-swept shorelines and seaward reef margins, often seeking refuge among rocks. Juveniles prefer pockets within the intertidal reef crest, while adults reside along ridges between surge channels. Their diet primarily consists of benthic algae. Additionally, juveniles inhabit sheltered ocean bays and shallow low boulder-reefs located above sand levels. They are also common in clear-water reefs, particularly in gutters and the upper edges of drop-offs.
Reproductively, the Whitebar Damselfish is oviparous, engaging in distinct pairing during breeding. The eggs, which adhere to the substrate, are demersal, and the males are responsible for guarding and aerating them. This species is diurnal.
Geographically, the Whitebar Damselfish is found throughout the Indo-Pacific region, spanning from the 🌊 Red Sea and East Africa to the Marshall and Pitcairn island groups, extending northward to 🇯🇵 Japan and southward to 🇦🇺 Australia.
The genus name, Plectroglyphidodon, originates from Greek: "plektron" meaning anything to strike with or spur; "glyphis," meaning carved; and "odous," meaning teeth.
