📖 Overview

Occurs on upper part of sand and mud banks, usually on reef flat areas, just before sloping down in depths from 7 m down to about 15 m. Found in spread out groups, often with X. pentadactylus in the same general area, but this species grows much larger and dominates . Dives into sand to sleep safely at night or to hide when alarmed . But the biggest males swim over large areas and move away quickly when approached by divers rather than diving into the bottom .
