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); microthrix: Specific name refers to the fine hairlike secondary filaments of the illicium.

Estimates based on models

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): 3.8 ±0.7 se; based on size and trophs of closest relatives

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