📖 Overview

Found over a wide range of habitats like seagrass beds and outer reef slopes , also on mud bottoms. Solitary . Feed on small fishes and crustaceans (mainly stomatopods and crabs). Sexual transition from female to male occurs between 35-45 cm, but not all females change sex. Mature individuals form spawning aggregations . E. chlorostigma is closely related and very similar to E. polylepis and E. gabriellae which seem to replace it in the northwestern Indian Ocean. Solitary .
