Malacostraca | Decapoda
Environment: milieu / climate zone / depth range / distribution range
Benthic; brackish; depth range 8 - 95 m (Ref. 8), usually 20 - 60 m (Ref. 409). Tropical; 36°N - 35°S, 72°E - 165°W
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - ? cm Max length : 15.4 cm BL male/unsexed; (Ref. 409); 18.8999996185303 cm BL (female); max. published weight: 18.00 g (Ref. 116487)
Maximum carapace length: 3.5 cm (male); 4.2 cm (female) (Ref. 8). Common body length: 7.0 to 14.0 cm (Ref. 409). Minimum depth range from Ref. 111048. Subtidal (Ref. 106854). Found mainly in turbid waters down to a depth of 95 m over bottoms of mud, sandy-mud or silt. Juveniles are found in estuaries and backwaters, also in seagrass beds, mangrove banks, mud flats, and open channels (Ref. 8) while adults are found in deeper waters (Ref. 10). Juveniles from a riverine mangrove are likely to obtain nutrition from phytoplankton and possibly epiphytic algae than from mangrove leaves or detritus (Ref. 105141). Omnivore (Ref. 116259). Spawning occurred throughout the year with peak in September (Ref. 94179).
