Max length : 70.0 cm TL macho / no sexado; (Ref. 4426)

Biología     Glosario (por ej. epibenthic)

Range from coastal waters to about 300 m depth (Ref. 3167). Feed on all kinds of bottom animals (Ref. 3167). 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). About 80-154 eggs are laid by an individual in a year (Ref. 41305).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Spawns throughout the year with maximum number of egg-cases laid in late spring and summer, embryos developing in about 4 months (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
