Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 11-14; Espinas anales 0; Radios blandos anales: 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).

Biología     Glosario (por ej. epibenthic)

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).
