Etymology: Dasyatis: Greek, dasys = rough, dense (Ref. 45335).
Environment / Climate / Range
Marine; brackish; demersal; amphidromous (Ref. 51243). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm 18.7, range 19 - ? cm
Max length : 29.0 cm WD male/unsexed; (Ref. 9840); common length : 18.0 cm WD male/unsexed; (Ref. 4832)
Indo-West Pacific: India to southern Japan, Myanmar, Malaya, Indonesia, China and Indo-China.
Common in estuaries (Ref. 4832). Feed on bottom-dwelling organisms (Ref.50449)- primarily small crustaceans, but also small fishes (Ref.58048). Ovoviviparous (Ref. 50449). Landed in very large quantities as by-catch in the bottom trawl and trammel fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).
