Maximum diving depth of 20.5 m recorded from Australia (Ref. 81173). Found in inshore waters, in bays and channels (Ref. 1394). Favors areas with warm shallow water, inshore and reefal seagrass beds (Ref. 936), particularly on fine sand (Ref. 86921). Occurs in small groups of up to 6 individuals; though, an exception of a herd of to 600 individuals was once recorded between Bahrain and Qatar (Ref. 801). Population estimates in the Persian/Arabian Gulf range from 5800 to 7300 individuals. Has a larger range than previously known, where their present range may be about 74% of the historical range (Ref. 114880). Feeds on a variety of seagrasses (Ref. 936). Almost entirely dependent on seagrass for food (Ref. 114880). Preyed upon by tiger sharks (Ref. 49538). Faces threats in the Persian/Arabian Gulf such as dredging, trawling and land reclamation, all damaging their critical seagrass habitats (Ref. 114880).
