Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 115 - 130; Anale stekels: 0; Anale zachte stralen: 87 - 102. Differs from Paraplotosus albilabris and P. muelleri in having a tall, sail-like first dorsal fin and extremely long nasal barbels, which extend posteriorly to the basal third of the pectoral fin or beyond (Ref. 31103). Small juveniles have a unique coloration consisting of a black head and body with a broad white to yellow margin on the first dorsal fin and continuous dorsal-caudal-anal fin (Ref. 31103). Adults entirely black (Ref. 31103).
Body shape (shape guide): elongated.
Restricted to coastal reefs (Ref. 31103). Secretive, found in reef holes or under large rocks (Ref. 31103). Presumably nocturnal (Ref. 31103). Feeds on gastropod mollusks and crustaceans (Ref. 31103).
