Tamanho / Peso / Idade
Maturidade: Lm ?  range ? - ? cm
Max length : 115 cm TL macho/indeterminado; (Ref. 114953)
Commonly found near coast. Demersal on inner continental shelf. Feeds mainly on fishes, crustaceans and cephalopods (Ref. 114953). 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 14.5-16.0 cm long and 7.0-7.5 cm wide (Ref. 41249, 41253, 41298). Males reaches maturity at ca. 47 cm TL, females at ca. 69 cm TL; young hatch at 9-10 cm TL (Ref. 114953).

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).
