Neoglyphidodon melas (Cuvier, 1830)

Adult Coloration

Neoglyphidodon melas can be identified by its dark blue-black body coloration when it reaches adulthood.

Juvenile Coloration

In contrast, juvenile individuals are pale blue, with a yellow stripe running across their dorsal surface, yellow-outlined caudal fin rays, and bright blue anal and pelvic fins that have dark outer rays.

Fin Spine and Ray Count

This species has 13 dorsal spines, 13 to 15 soft dorsal rays, 2 anal spines, and 12 to 15 soft anal rays.

Body Shape and Locomotion Adaptations

Its body is laterally compressed, which lets it move through the narrow crevices of coral reefs, and its long pectoral fins provide additional support for maneuverability and agility.

Size and Weight

Mature Neoglyphidodon melas can grow between 11.8 and 18 centimeters in length and reach a weight of 100 grams.

Geographic Distribution

Neoglyphidodon melas is distributed across the entire Indo-Pacific region, and has been recorded in the Red Sea, East Africa, the Indo-Malayan archipelago, the Ryukyu Islands, China, the Philippines, Palau, New Guinea, the Solomon Islands, Vanuatu, and northern Australia.

Habitat and Diet

Within this range, the species inhabits coralline rocky lagoons and marine reefs that host soft corals, which make up most of this fish’s diet.

Depth Range

It is most often found at depths between 1 and 12 meters.
