Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; amphidromous (Ref. 51243); depth range ? - 40 m (Ref. 9772). Tropical
Indo-West Pacific: Pakistan, India, Sri Lanka, through the East Indies, to China. Records from the east coast of Africa were probably based on misidentifications as this species does not occur there (Ref. 4373). Range extends westwards to the Persian Gulf (Ref. 9772).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 9 - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 2872); common length : 20.0 cm TL male/unsexed; (Ref. 2872)
Inhabits coastal waters and estuaries. Feeds on invertebrates, particularly benthic worms. Marketed fresh and dried salted.
