Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 8 m (Ref. 31103). Tropical

Max length : 26.8 cm SL male/unsexed; (Ref. 31103)
Morphology | Morphometrics
soft rays: 80 - 95. Differs from P. albilabris in having a taller dorsal fin and larger eye (Ref. 31103). Differs from Paraplotosus butleri in having a shorter dorsal fin and shorter nasal barbels, rounded pectoral fin shape, fewer procurrent caudal fin rays, and fewer gill rakers. Brown in color, belly area and ventral surface of head whitish (Ref. 31103).
Restricted to turbid coastal reefs of mainland Australia and nearby islands (Ref. 31103). Presumably nocturnal (Ref. 31103). Feeds on gastropod mollusks and crustaceans (Ref. 31103).
