Mitchell's Emperor

📖 Overview

Found in an area consisting of a gully with volcanic black sand and rubble bottom, from the shoreline shallows to about 30 m depth on a relatively steep slope. About 10 individuals (size from about 10.0-20.0 cm SL) were observed around a large submerged tree trunk, lying horizontally across the gully in 20-25 m depth. When pursued with a spear, the fish retreated down the slope. Thus, it is possible that the species is normally found in deeper water, accounting for the lack of previous observations by us despite many hours of diving near the type locality over the past two decades, routinely to depths of 40-50 m .
