Maturity: L_m ? range ? - ? cm
Max length : 66.0 cm TL पुल्लिंग / अलिंग; (Ref. 114953)

Occur over soft bottoms of the continental shelf and slope (Ref. 7300, 75154). Mainly feeds on benthic crustaceans, small fishes and octopi (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 measure 7.0 cm long and 3.8 cm wide (Ref. 6778). This species reaches maturity after 5 years. Maturity size of males at ca. 45 cm TL; young hatch at ca. 11 cm TL (Ref. 114953). Utilized as a food fish (Ref. 6871).

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).

Estimates based on models

Preferred temperature (Ref. 123201): 11.9 - 17, mean 14.5 °C (based on 78 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).
