Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Disc broadly rounded. Upper surface of disk is pale and has dark spots. Ocellus on each pectoral fin usually oval. Ocelli are closer (Ref. 7251). Lower surface white without dark markings (Ref. 6902).

Benthic (Ref. 51024). 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).

Estimates based on models

Preferred temperature (Ref. 123201): 20.1 - 27.6, mean 24.8 °C (based on 34 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 3.7 ±0.4 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 (40 of 100).
