Ecology
Benthic; brackish. Tropical
Indo-West Pacific: from India to Vanuatu; north to Viet Nam and south to eastern Java.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 10.0 cm SHL male/unsexed; (Ref. 348); common length : 7.0 cm SHL male/unsexed; (Ref. 348)
Widely collected as food in Asia (Ref. 348). Brackish to almost fresh water areas of mangrove swamps. Diurnal rhythm of activity and inactivity strongly depending on the tides and rainfall. Can survive during drought periods by aerial respiration at the posterior mantle margins (Ref. 348).
