البيئة
بحري القاع. Subtropical; 38°N - 10°N, 62°E - 138°E (Ref. 114953)
Indo–West Pacific; Pakistan to East China Sea (Shanghai), including Taiwan and possibly Japan and Philippines.
Conservation status maybe of concern in Northwest Pacific because of its inshore benthic habitat, low abudance, and the presence of intensive demersal fisheries (Ref. 47737).
