Etymology: Rhynchactis: Greek, 'rhynch' = beak or snout + Greek, 'aktis' = ray (in reference to the illicium that arises near the tip of the snout) (Ref. 86949); macrothrix: Specific name refers to the relatively long secondary filaments of the illicium.

Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 4; Raggi anali molli: 3. Length of illicium 109-144% SL, distal tip bearing 3-4 small unpigmented filaments, some with tiny distal swelling; distal 28-57% illicial length bearing series of 11-20 secondary filaments, five longest filaments measuring 6-15%SL; each secondary filament with 1-2 unpigmented terminal filaments, some with tiny distal swelling; large specimens (110-113 mm) with secondary filaments darkly pigmented to base of terminal filaments, divided on each side by a narrow, well-defined longitudinal transparent band (Ref. 86949).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 9, mean 6.1 °C (based on 368 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

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