Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 5; Anal soft rays: 9 - 10; Vertebrae: 32 - 33. The following unique characters separate this species from all other species of Tatia: postcleithral process well developed, reaching almost to a vertical through the dorsal-fin origin; orbital diameter 37.0-42.9% HL; and snout length 23.1-28.9% HL . Can be further distinguished by the following features: narrow elliptical cranial fontanel; ribs 7; nasal ossified with wide medial flanges partially sutured to lateral margin of mesethmoid; coloration variable, sides of body usually dark with light, rounded spots or dots, or sometimes uniformly pale brown; toothed prevomer in examined large adult specimens (Ref. 79512).

Reaches sexual maturity above 5.42 cm SL (Ref. 79512).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 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).
