Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 120 cm TL male/unsexed; (Ref. 89972)
Vertebrae: 128 - 134. With tail 45-48% and head 13-16% of TL; dorsal fin arising well behind pectoral tips; pectoral fins fan-shaped, not elongate; snout short, about 3.4 in jaw; jaws elongate, about 2.3-3 in head; nostrils in short tubes in upper lip and closely associated; cirri of labial fringe unbranched, short and stubby; flesh above and behind eye laterally elevated as a ridge; dorsal head profile depressed and constricted behind eyes, the flesh forming a lateral eave behind dorsal margin of eye; head pores and lateral-line pores apparent; free sensory neuromasts visible as rows of white spots on nape; teeth conical; coloration in life variable; fins pale except dorsal notably dark basally with a pale margin; lateral-line pores in distinct dark spots; numerous dark spots above lateral line on body (Ref. 42180).
Found over sandy areas, usually near or within coral or rocky reefs (Ref. 42180, 75154). Feeds on fishes and crtustaceans (Ref. 89972). Benthic (Ref. 58302, 75154). At night, it is usually encountered with its head and even the anterior portion of its body protruding from the substrate at night (Ref. 42180). At day time, it often remains buried with only the tip of its snout and the top of its head projecting from the sand or mud (Ref. 42180).

Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
