Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 2334)
Found over sandy bottoms of coastal areas and also in areas with some seagrass or algae. Ranges to a depth of over 18 m (Ref. 9710). Usually in large spread-out groups on upper slopes of sand and mud banks with males defending its section that has numerous females (Ref. 48636). Dives into sand to sleep safely at night or to hide when alarmed (Ref. 90102). When threatened, it dives head-first into sand; may take some time to emerge again. Feeds mainly on hard-shelled prey, including mollusks and crustaceans (Ref. 5374). Minimum depth taken from Ref. 9710.
