Environment: milieu / climate zone / depth range / distribution range
Écologie
marin démersal. 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).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 35.0 cm TL mâle / non sexé; (Ref. 114953); common length : 30.0 cm TL mâle / non sexé; (Ref. 114953)
Preorbital length about equal to preoral length (and much greater than prenasal length), and dark brown spots that are usually greater than eye diameter over a brown background (Ref. 49866).
Found in continental waters, both inshore and offshore (Ref. 9912). Biology little known (Ref. 9912). Maturity size of males at ca. 24 cm TL, birth size at ca. 11 cm TL (Ref. 114953).
