Tamaño / Peso / Age

Maturity: Lm ?  range ? - ? cm
Max length : 75.0 cm TL macho / no sexado; (Ref. 100834); peso máximo publicado: 2.5 kg (Ref. 100834)

Biología     Glosario (por ej. epibenthic)

Inhabit inshore waters (Ref. 3167). Depth range to 170 m (Ref. 04426), and from 333-343 m in the eastern Ionian Sea (Ref. 56504). Feed on all kinds of benthic 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). Egg capsules are 4.5 cm long and 3.0 cm wide (Ref. 41304). Minimum depth range (Ref. 114953).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Spawning peak in summer to early autumn with 30 to more than 100 egg-cases per year depending on the size of the female (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
