Etymology: Trachinocephalus: Greek, trachys, -eia, -ys = rough + Greek, kephale = head (Ref. 45335). More on author: Forster.
Issue
Species complex with Trachinocephalus myops formerly cincumtropical is now restricted to the Atlantic Ocean; T. trachinus resurrected for the Indo-West Pacific Ocean; and, <>T. gauguini found in the Marquesas Is. (Ref. 110386). Information in this species record for modification.

Length at first maturity / Size / Gewicht / Leeftijd
Maturity: Lm ?, range 19 - ? cm
Max length : 40.0 cm TL mannelijk/geslacht niet bekend; (Ref. 9710); common length : 25.0 cm TL mannelijk/geslacht niet bekend; (Ref. 5217); Maximaal vermelde leeftijd: 7 jaren (Ref. 36558)
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 11-14; Anale stekels 0; Anale zachte stralen: 13 - 18. Snout very short; mouth very oblique; body with alternating narrow dark-edged pale blue and yellow stripes; oblique black spot at the upper end of the gill opening (Ref. 2334). Eye far forward (Ref. 26938).
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). Benthic at 3-388 m (Ref. 58302). Rest on or more often burrow into substrate, leaving eyes exposed (Ref. 4472, 48635). 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).
