Ecologia
marinhas demersal; intervalo de profundidade 0 - 170 m (Ref. 6871), usually 0 - 40 m (Ref. 6871). Temperate; 37°S - 45°S, 140°E - 150°E (Ref. 114953)

Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 55.0 cm TL macho/indeterminado; (Ref. 114953)
Occur on soft bottoms of the continental shelf (Ref. 7300, 75154). Feed on benthic fishes and crustaceans (Ref. 6871). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 4.4-6.3 cm long and 3.2-3.8 wide (Ref. 41308). Males reaches maturity at ca. 39 cm TL, females at ca. 42 cm TL; young hatch at ca. 10 cm TL (Ref. 114953).
Life cycle and mating behavior
Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
