Dorsal soft rays (total): 78 - 81; Anal soft rays: 62; Vertebrae: 47 - 49. Tuamotuichthys marshallensisdiffers from T. bispinosus in the following characters: downward-directed part of the opercular spine hidden (vs. free); precaudal vertebrae 11 ( vs. 13); dorsal fin origin above vertebra no. 5 (vs. no. 8); hypobranchial rakers of anterior gill arch developed as one large or five smaller plates provided with small spines (vs. hypobranchial without rakers or plates); soft interorbital 5.8-6.3 % SL (vs. 3.8 % SL); maximum head depth 20.0–-1.5 % SL (vs. 13.5 % SL); body depth at origin of anal fin 18.5-20.5 % SL (vs. 14.5 % SL); head pores present on occiput and upper preoperculum (vs. absent); interorbital and occipital head pores present (vs. absent); no scales on top of head (vs. scales present); dorsal rim of otolith high (vs. rim flat) (Ref. 57891).

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=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 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).
