📖 Overview

This species appears to be restricted to relatively shallow (3-10 m) reef areas protected from wave exposure. Type specimens were collected exclusively from within beds of Halimeda macroalgae growing beneath branching Acropora coral stands. It is apparently the only species of the genus to be limited to this habitat .
