Malacostraca | Decapoda
Environment: milieu / climate zone / depth range / distribution range
Benthic; brackish; depth range 10 - 55 m (Ref. 8), usually ? - 20 m (Ref. 10). Tropical, preferred 28°C (Ref. 107945); 28°N - 29°S, 39°E - 168°E (Ref. 356)
Indo-West Pacific: from Kenya and the Persian Gulf to Hong Kong and Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - ? cm Max length : 24.0 cm TL male/unsexed; (Ref. 8); max. published weight: 50.00 g (Ref. 116487)
No dark brown transverse bands on the carapace and abdomen, which are uniformly glabrous. Uniformly high proximal part of triangular rostrum is particular in fully grown female. Rostrum usually armed with 7 or 8 dorsal and 5 or 6 ventral teeth. No lateral spines on telson. Color: in life, cream to yellow, sometimes minutely speckled with brown, olive green or light green pigments. Brown banded antennules; brown antennae not banded; legs and pleopds are yellowish, sometimes tinged with brown or pink; uropods with combinations of yellowish green and brownish shades. Upper margin of rostrum is fringed with brown in fully grown individuals.
Maximum depth from Ref. 10. Maximum standard length: 24.0 cm (Ref. 356). Caught mainly by trawl, gill net, fish corral, push net and filter net (Ref. 10). Occurs in bottom mud or sandy-mud substrates in marine and estuarine environments (Ref. 8). Inhabits shallow open sea or in the mouth of a river and bay areas where water is more or less turbid (Ref. 374). Adult species periodically form aggregations or 'schools' offshore (Ref. 100847). Omnivore (Ref. 116259). Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833). Spawning happened throughout the year with one peak in September (Ref. 94177).
