Etymology: Limatulichthys: Latin, limatus, -a, -um = sandpapered + Greek, ichthys = fish; nasarcus: Derived from the Latin nasus, meaning snout, and arcus, meaning bow-shaped, in reference to the rounded snout of the species when compared to its congener Limatulichthys griseus..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 5. Limatulichthys nasarcus differs from L. griseus by the possession of the following characters: anterior abdominal plates half the size of those at center of abdomen (vs. plates similar in size); spots across the entire dorsum, including snout and head, less than half of diameter of naris (vs. indistinct spots larger or equal than diameter of naris); lateral portion of head and opercle with dark well-defined spots, larger than those on dorsum (vs. spots on lateral portions of head and opercle equal in size to those on remainder of body); profile of snout in dorsal view broadly rounded (vs. acutely triangular); head longer (21.4-24.2 SL vs. 17.7-21.0%); and longer anal fin (15.7-18.0 SL vs. 13.7-15.6%) (Ref. 97714).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00646 (0.00235 - 0.01774), b=3.04 (2.80 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

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