McCulloch’s Scalyfin is a reef-associated fish found in the subtropical waters of the Eastern Indian Ocean, specifically along the western coast of Australia between the Recherché Archipelago and Abrolhos Islands. They inhabit rocky reefs and are typically found at depths ranging from 2 to 25 meters. This species can grow up to 20 centimeters in length. Its body is short, deep, and compressed, featuring 13 dorsal spines and 18 to 19 dorsal soft rays, along with 2 anal spines and 14 to 15 anal soft rays. These fish are known for their oviparous breeding behavior, where distinct pairs form during the breeding season. The eggs are demersal, meaning they adhere to the substrate, and the males play an active role in guarding and aerating them. Divers might encounter McCulloch’s Scalyfin while exploring rocky reefs, where they exhibit territorial behavior. The conservation status of McCulloch’s Scalyfin is assessed as Least Concern by the IUCN. They are harmless to humans and do not have any significant threats impacting their populations.
