seewasser demersal; tiefenbereich 20 - 325 m (Ref. 114953). Temperate; 27°S - 36°S, 150°E - 154°E (Ref. 114953)

Western Pacific: endemic to eastern Australia.

Length at first maturity / Size / Gewicht / Alter

Maturity: L_m 45.5, range 43 - 48 cm
Max length : 55.0 cm TL Männchen/unbestimmt; (Ref. 114953)

Found on the continental shelf (Ref. 6871, 75154). 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 5.7 cm long and 3.2 cm wide (Ref. 41308). Males reaches maturity at 43-48 cm TL. Biology poorly known; probably have suffered population declines in recent years (Ref. 114953).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

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): 18.6 - 21.4, mean 20 °C (based on 8 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): 4.1 ±0.7 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
