Size / Gewicht / Alter

Maturity: L_m ? range ? - ? cm
Max length : 64.9 cm TL Männchen/unbestimmt; (Ref. 75648); 69.5 cm TL (female)

Inhabits continental shelf at 20-120 m, rarely found deeper to 390 m. Feeds mainly on crabs, shrimps and other benthic crustaceans. Reproduces throughout the year and reaches maturity at 5-6 years (Ref. 114953). Lengths of adolescent males varied from 41.5-53.4 cm TL, adult males from 49.8-64.9 cm TL; smallest juvenile 22.0 cm TL. Egg cases were observed to be about 5.6-6.9 cm long with a maximum width of about 4.5-5.3 cm TL (Ref. 75648).

Estimates based on models

Preferred temperature (Ref. 123201): 14.2 - 27.7, mean 18.1 °C (based on 764 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

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
