Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 39 - 41. Trichonotus halstead is similar to T. setiger but has a beautifully colored dorsal fin (Ref. 48636). No free pterygiophores under dorsal fin (Ref 12934).

Like other sand divers, it occurs on sand slopes with strong currents at times (Ref. 48636). Minimum depth reported from Ref. 26146.

Estimates based on models

Preferred temperature (Ref. 123201): 27.5 - 29, mean 28.2 °C (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.48 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
