Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Upper surface of disc is largely smooth except around the eyes. Pale coffee brown except for a translucent area either side of rostral cartilage. Pale areas around the mouth, gill openings and tail (Ref. 6902).

Solitary (Ref. 26340). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 14.4, mean 9.9 °C (based on 87 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.5 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): Low vulnerability (23 of 100).
