Max length : 76.0 cm TL macho / no sexado; (Ref. 2850); common length : 45.0 cm TL macho / no sexado; (Ref. 9261)
Common in inshore waters from approximately 15 m and in shallow bays, sometimes in deep water (Ref. 2850, Ref. 114953). Feeds on small benthic invertebrates, polychaete worms and shrimps (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 7.0-8.5 cm long and 6.5-7.6 cm wide (Ref. 41300). Males reaches maturity at ca. 47 cm TL, females at 52 cm TL; young hatch at ca. 15-23 cm TL (Ref. 114953).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
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).
