Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 10 - ? m. Subtropical; 28°S - 34°S
Southeast Atlantic: Mossel Bay to Natal in South Africa.
Length at first maturity / Size / Weight / Age
Maturity: Lm 57.5  range ? - 70 cm
Max length : 200 cm TL male/unsexed; (Ref. 3198); common length : 100.0 cm TL male/unsexed; (Ref. 3507); max. published weight: 80.0 kg (Ref. 4537)
Found near rocky banks in coastal waters including estuaries. Adults solitary and territorial. Feeds on octopus, crabs and fish, especially Spondyliosoma. The flesh is highly esteemed, but the liver is poisonous due to high vitamin A content which causes hypervitaminosis. Popular angling fish. Largest of the porgies.
