Etymology
Chromis: from Greek, chroemo = to neigh. A name dating to Aristotle, referring to a drum (Sciaenidae) and its ability to make noise; Later applied to this damselfish and subsequently expanded to embrace dottybacks, cichlids and wrasses (all perch-like fishes once thought to be related).
kennensis: from Kenn Reef, Coral Sea, Australia. The type locality for this fish.
Orginal description: Chromis kennensis Whitley, 1964 - Type locality: Kenn Reef, Coral Sea; October 2, 1960. Dr. D. F. McMichael.
Distribution
Southwest Pacific Ocean: Coral Sea, Lord Howe Island, eastern Australia, New Caledonia and Tonga.
Biology
Adults inhabit lagoon and outer coral reefs, boulder bottoms and lava cliffs, in small to large aggregations. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
