Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 0. Caudal ends in a hardened point. Ogivale head, small eyes near buccal joint at end of snout. Buccal slit short, snout prominent covered with villi. Gill slits lateroventral, crescentiform. Thin dorsal and anal fins, in groove; dorsal origin behind gill slits (predorsal length 11.5-16.9% TL); anal origin immediately behind anus. Pores of lateral system and cephalic slightly rimmed. One median pore on the supraorbital joint; 57-64 pores on lateral line before the anus. Vertebrae: 149-162. Dark brown back and dorsal base, whitish belly.

Mainly nocturnal. During the day, this fish lies buried in the sediment with the head out.

Estimates based on models

Preferred temperature (Ref. 123201): 21.4 - 28, mean 27.1 °C (based on 208 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00091 (0.00039 - 0.00215), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).
