Etymology: Grammatostomias: Greek, gramma, atos = signal, mark + Greek, stoma = mouth (Ref. 45335); ovatus: Name from Latin 'ovatus' for oval, referring to the typical ring-shaped pattern of luminous tissue on the side.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 18; Anal soft rays: 20. This species is distinguished by the following characters: pectoral-fin rays 6, the last of which is separated, and a luminous tissue strip on the side in the form of a longitudinally elongated oval, and ending far beyond the level of attachment of ventral fins (Ref, 123295).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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