Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

Longer rostral cartilage. Long interspace between dorsal fins. Upper surface of disc, pelvic fins and tail pale pinkish brown without distinctive markings. Lower surface plain whitish, later becoming clouded with chocolate brown (Ref. 6902).

Solitary (Ref. 26340). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 11.4 - 18.8, mean 14.2 °C (based on 14 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

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
