Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 73 - 78; Spine anali: 0; Raggi anali molli: 49 - 60. Body on ocular side brownish with darker spots and blotches; a series of blotches along dorsal and ventral body margins; elongated anterior dorsal-fin rays white, remainder of dorsal fin, anal fin, and caudal fin brown; pectoral fin dark. Blind side of body whitish. First 12-15 (rarely 10-11) dorsal- fin rays greatly elongated. Pectoral fin on blind side absent or rudimentary. Pelvic fin on eyed side elongated. Caudal fin with 16 unbranched rays and rounded margin.

Inhabits silty sand or mud bottoms (Ref. 3132, 48637). Feeds on benthic animals (Ref. 9792). Flicks the long dorsal filaments on the front of the head when alarmed, looking just like the sticky threads that are produced by a holothurian when handled (ref. 48637).

Estimates based on models

Preferred temperature (Ref. 123201): 22 - 28.6, mean 27.3 °C (based on 858 cells).

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

Bayesian length-weight: a=0.01622 (0.00604 - 0.04358), b=2.94 (2.71 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): Very high.
