Max length : 57.0 cm TL jantan/; (Ref. 111281); Berat maksimum terpublikasi: 815.70 g (Ref. 125279)

Bottom-dweller that feeds on invertebrates and bony fish. 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 4.8-6.6 cm long and 2.9-3.7 cm wide (Ref. 41249, 41253, 41298). Depth range given by H. Ishihara (pers.comm. 07/07).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

Oviparous, paired eggs are laid mainly at night (Ref. 44760). Batches of eggs are laid in three to six-day interval on sand bottom. 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): 9.8 - 26, mean 22 °C (based on 123 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00288 (0.00178 - 0.00467), b=3.23 (3.10 - 3.36), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on diet studies.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec = 40-150;).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

kategori harga (Ref. 80766): Medium.
