Benthic; brackish; depth range 2 - 300 m (Ref. 8), usually ? - 60 m (Ref. 10). Tropical, preferred 27°C (Ref. 107945)
Indo-West Pacific and the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm 1.0, range 1 - 1 cm Max length : 18.0 cm TL male/unsexed; (Ref. 8); 22.7999992370605 cm TL (female); common length : 25.0 cm TL male/unsexed; (Ref. 374); max. published weight: 130.00 g (Ref. 374)
Carapace and abdomen uniformly glabrous. More or less straight rostrum armed with 7 or 8 dorsal and 3 ventral teeth. Inclined downward and anteriorly hepatic carina. White and red transverse stripes present as bands in the antennae. Adrostral carina reaching well beyond epigastric tooth.
Maximum depth from Ref. 801. Occurs on mud, sandy-mud or sandy-grit substrates (Ref. 10), seagrass, mangrove and among shells (Ref. 121467). Prefers marine (adults) and estuarine (juveniles) environments in subtropical and tropical climates (Ref. 8). Forms small shoals. Predominantly nocturnal and buries in substrate during day time (Ref. 10). Postlarvae settle exclusively in seagrass beds (Ref. 84594); Juveniles also seek refuge in seagrass beds (Ref. 106924). Feeds on seagrass (Ref. 84594), diatoms, algae, (Ref. 104907), bivalves, gastropods, ophiuroids, crustaceans and polychaetes (Ref. 104903). Spawns throughout the year, with peak from July to September (Ref. 116211).
Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
