Margins of median fins black (Ref. 2798); characterized by pale grey body color with three large dark brown blotches on side; head and body with faint brown scribbling; elongate and filamentous second and third dorsal spines; rounded caudal fin, slightly shorter than head; longitudinal scale series 29-30; head without scales; ctenoid body scales except cycloid on breast, base of pectoral fin and anterior part of abdomen; midline of nape without scales or 1-2 scales just before origin of dorsal fin; depth of body 3.2-3.4 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Solitary (Ref. 90102). Found over silty (Ref. 58652) and muddy bottoms around inner reefs. Common in mangroves and enter estuaries and rivers (Ref. 4343). Toxin concentrated in the skin. Contains 28.7 µg/g tetrodotoxin in the internal organs while the flesh holds 1.7 µg/g (Ref. 5719).

Estimates based on models

Preferred temperature (Ref. 115969): 25 - 29.3, mean 28.4 °C (based on 2783 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00473 - 0.02214), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
