Ecologia
marinhas 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).
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 35.0 cm TL macho/indeterminado; (Ref. 114953); common length : 30.0 cm TL macho/indeterminado; (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).
