背的軟條 (總數) : 11 - 14; 臀鰭軟條: 13 - 18. This species is distinguished from its congeners by the following characters: snout length (LSn) 40.4-108.5% eye diameter (DE), mean 74.8% (vs. mean 40.1% in T. gauguini and 79.1% in T. trachinus); LSn 15.0-26.0% body depth (DB), mean 21.2 (vs. mean 14.7% in T. gauguini); interorbital width 5.2-12.0%, mean 8.7% LH (vs. mean 5.6% in T. gauguini); DE 11.0-22.6% LH, mean 16.6% (vs. mean 19.6% in T. gauguini and 15.7% in T. myops); length of the last dorsal-fin ray 8.7-11.8% LS, mean 10.1% (vs. mean 10.8% in T. gauguini and 9.4% in T. myops); anal-fin rays 13-18, mode 16 (vs. mode 14 in T. gauguini and 15 in T. myops); pectoral-fin rays 11-13, mode 12 (vs. mode 11 in T. gauguini); predorsal scales 14-18, mode 16 (vs. mode 17 in T. myops). differs further from T. gauguini and T. myops by the deep mitochondrial distances (15.7-19.0 and 15.1-17.8%, respectively) (Ref. 110386).

Occurs in estauries and inshore waters to 200 m (Ref. 110386); benthic at 3-388 m (Ref. 58302). Found near shore above 40 m over sandy bottoms of deep outer reef slopes (Ref. 11230). Reported to be common in estuaries (Ref. 11228, 48635). Rest on or more often burrow into substrate, leaving eyes exposed and when disturbed, it may swim a short distance but quickly buries itself again (Ref. 48635). Feed on fishes (Ref. 5213) and small crustaceans (Ref. 36558).

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=0.02291 (0.01286 - 0.04082), b=3.39 (3.23 - 3.55), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

營養階層 (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
