Environment: milieu / climate zone / rango de profundidad / distribution range
Ecología
marino demersal. 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).
Tamaño / Peso / Age
Madurez: Lm ? range ? - ? cm
Max length : 35.0 cm TL macho / no sexado; (Ref. 114953); common length : 30.0 cm TL macho / no sexado; (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).
Body shape (shape guide): other.
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).
