Actinopterygii (ray-finned fishes) > Scorpaeniformes
(Scorpionfishes and flatheads) > Platycephalidae
Etymology: Platycephalus: Greek, platys = flat + Greek, kephale = head (Ref. 45335). More on authors: Waite & McCulloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 70 - 490 m (Ref. 6390). Subtropical; 27°S - 41°S
Indo-Pacific: endemic to the southern waters of Australia, from Marrawah in northwestern Tasmania to latitude 27°S off Western Australia. This species has been confused with Platycephalus speculator until recently.
Length at first maturity / Size / Weight / Age
Maturity: Lm 40.0, range 45 - ? cm
Max length : 70.0 cm TL male/unsexed; (Ref. 6390); 94.0 cm TL (female); max. published weight: 0.00 g; max. reported age: 20 years (Ref. 6390)
Occurs on the continental shelf and upper slope (Ref. 9563). Feeds primarily on fish, crustaceans and squid (Ref. 6390). Probably forms aggregations by sex (Ref. 27192). Sold as fresh, chilled, or frozen fillets in the domestic market.
